i know, i was kinda in shock the first time i saw ttd sway like that, i knew roller coasters flexed a little, but never that much.
and i could stand in line and watch Son of Beast give when a train goes through the swoop turn, and even though it's not as noticeble with the lighter trains, the turn to the right after the drop used give atleast a good three feet every time a tree would go through it.
