Thanks for the great trip report! I grew up in Arlington and called SFOT my home park for many years. It is truly a shame to have watched Texas Giant become what it is today. In the '90s, this ride was as good as a wooden coaster gets. The speed, transitions, layout, and 'magic carpet' ending were absoultely incredible. My last trip was in 2003 and I still had fun on the Giant, but from what I hear it has only gotten worse each year since. Still, it was my first 'adult' coaster and it will always have a special place in my heart (hence my screen name).
As for your other observations, I'd pretty much have to agree with you. Casa Magnetica was a very cool experience for me as a child, but I can see how it might seem lame to an older person. It was closed for many years and finally reopened a couple of seasons ago (I'm happy that it's still around). Titan is amazing, and I agree that KI could definitely use a coaster like that! Shockwave, Freeze, Batman, Superman, and the Mine Train are all great rides as well.
Overall, the park has a lot of history and some of the best rides around, but there are quite a few negative aspects as well. Their last coaster was in 2001, so I'm really hoping they add a new signature ride in the next few years.
Now living 2 hours away from KI (enough for me to call it my home park), I'd also have to say that it is far better than SFOT. Still, thanks for the report from my first home park.
