I know its been 3 months but I'm trying to get caught up however I thought I should point out that it appears the "Independence Week" ride got stuck underground before getting back to the station during the testing and never actually had a single rider. Love the series.
Yea I remember that there were some flaws in the trackdesign. The thing is that with those rodent type coasters, you really only want to have 1 lift in the whole track, otherwise you can indeed get cars stuck on the track after a breakdown. Well spotted though :)
