  1. I first visited KI in 1991. As a Brit, I did find International Street a bit cheesy. Now I live in Ohio and as a KI regular, I enjoy International Street, the Royal Fountain and the Eiffel Tower replica.
  2. My second guess is the urethane tires of the tractor wheels have worn unevenly, hence the rattle on the positive g-force loops. I don't know the life expectancy of a roller coaster wheel but removing a sample of wheels and measuring runout and concentricity could help determine if the wheels are part of the problem.
  3. Awesome, green-beer themed shrubbery. Maybe a hint the park will be open in time for St. Patrick's Day 2021? [emoji482][emoji3526][emoji40] Sent from my SM-G986U using Tapatalk
  4. Between about 1,300 and 400. Varies every ride.
  5. School is certainly more important than roller coasters! And math can be fun. Fact, without math not much in our modern society would exist. At least nothing fun! I find taking a few deep breaths and then holding my breath helps with high positive g-force turns, like the fainting circle. Also, holding your legs up, helps keep blood flowing to your brain. If your brain is starved of oxygen-rich blood, you can faint. I do not know much about Kentucky Kingdom. They once had a B&M stand-up coaster, but that got relocated. Maybe one day B&M will build a hyper coaster like Diamondback there
  6. Totally agreed. Probably why I thought something horrifically wrong, to suggest a supernatural occurrence, would be okay. Something mechanically wrong would not be acceptable.
  7. Yes, Orion is awesome. And, maybe Diamondback is better? For me, Diamondback is awesome in both the front and back rows. And, in the back row you even get a little wet, which I love! On Orion, try taking a deep breath and raising your legs before entering it's fainting circle.
  8. Finally, we can again night-ride The Beast in August
  9. I understand your frustration. Based on my observations, I believe Kings Island attendants are doing an awesome job of enforcing safety and health requirements. Most people would agree that face coverings are essential at this time. However, zero tolerance enforcement of face coverings is unrealistic.
  10. In the airline industry, flight attendants are responsible for ensuring passenger safety, and then passenger comfort. An analogy can be made with amusement park ride attendants. In the age of COVID-19, ride attendants are not only responsible for our safety, but now also our health. I have made five visits to Kings Island in 2020 and based on my observations believe ride attendants are doing an awesome job of fulfilling their responsibilities. To reinforce this, I am always polite to ride attendants and thank them for their assistance.
  11. As the rattle relates to Banshee, I just re-watched this 2016 POV: Even in this 2016 POV, you can see the camera rattles side to side on the positive g-force valleys. As I watch the POV, the frequency of the rattle is in tune with the rattle I experienced yesterday. The amplitude of the 2016 POV rattle does however appear less than I experienced yesterday. Note from the POV that in the valleys, the lengths of track between support frames are short and the support frames are also short. Based on inspection, the track structure in the valleys appears very stiff and will vibrate at a high frequency, which is desirable. Yet, it is in the valleys that the rattle occurs - like @Skibum compared to a jackhammer. So, either the foundations are bad (but as I’ve said before, I don’t believe they are) or the bogies of the trains are causing the rattle. Or is it something else?
  12. Agreed, Orion is definitely a front row ride.
  13. I wonder if the natural frequency of vibration of certain lengths of track interact with the bogies of the train, which in turn causes the rattle? B&M's track and support structures appear slender. This gives a very aesthetic appearance but can reduce the natural frequency of the track structure. Depending upon the amplitude of vibration of the track, this could cause loose wheel bearings to vibrate as energy is dissipated. Imagine pushing a shopping cart with a bad wheel, it is often noisy and can cause the cart to vibrate.
  14. I doubt Clermont Steel Fabricators would know the answer. Clermont fabricates and delivers the steel work specified by B&M. Clermont is not responsible for the design.
  15. Another thing to consider is that B&M probably does not design the foundations, but rather they performance specify loads that must be resisted and anchor bolt patterns. Kings Island (or a General Contractor working for Kings Island) would then work with a local subcontractor to design and install the foundations, while the steel work of the coaster is being fabricated. If the subcontractor did not take foundation settlement into account in the design, then yes significant long-term differential settlement of the track could cause the 'rattle'.
