Maybe it shook you so much it rearranged your memory. Gwazi was one of the roughest wooden coasters I've been on.
I didn't know it was recently retracked, but you may want to keep that in mind. If it was one of your roughest, you must not have been on very many wooden coasters. My home park has GASM and GA Cyclone, and I can already say both of those are rougher than Gwazi.
Wes is from Socal. So he's been on some bad woodies.
