I know there were problems with Avalanche Run/Disaster Transport from sand on the beach blowing on to the track. I ran across another bobsled coaster - this one in France - which seems to have a perforated track which would allow sand, water, and other debris to fall through. Was this a later innovation or simply just a different design? This particular coaster also seems longer in length and a bit faster in speed. Below are links to RCDB and YouTube for the Trace Du Hourra coaster

Avalanche at KD is similar:

I have also heard the "sand issue" was an inaccurate theory by enthusiasts of why AR was enclosed.

Having never been to Knoebels, I wonder what kind of stuff is gonna mess up Flying Turns (if and when they ever finish it).

Other rumors for why Avalanche Run was enclosed are:

1. Dick and the gang took a trip to Disney. Dick fell in love with Space Mountain and told the crew to get to work for Cedar Point's own version. Disaster Transport was born.

2. Judy, Dick's wife, complained that the ride was too loud for being right next to their house.

I think number one is the most likely.

Then don't build your house by an amusement park! Haha

2. Judy, Dick's wife, complained that the ride was too loud for being right next to their house.

This sounds pretty likely.

I like bobsled style coasters. They are fun and a nice change from all the speed and g-force. Avalanche, Disaster Transport, and space Mountain are the three that I have been on. Kings Dominion's is a nice paced coaster and I think it;s a lot fun.

Sometimes I just need a break from the major coasters at KD, this provides it for me.

I don't beleive any of the Space Mountains are bobsled coasters.
