Those that have bottomed out, nosed in, or tail dragged; what happened? What kind of environment were you in? What type and size of bus where you in? Do you think a bus with a different layout could have made it through? Was there damage? Have there been places you wanted to go but didn't dare, because of the layout of your bus?
My previous bus was a 1969 40' 10 wheeled Gillig that I though could go through anything - until I tried to drive out of a gas station that had an exit ramp that was angled on both sides. The kick down linkage, which was connected to the throttle, caught on the peak which floored the throttle and smashed the transmission into the ramp!
There was much wailing and gnashing of teeth.
