its been a few years since ive been in san diego .. But if memory serves Be careful around the MT .. ( use to be a right of passage for my crew) the locals use to love throwing crap on the roads ( sand oil etc) to prevent bikers from going up and down it ... theres a crew that meets up every sat at the gas station right off otay mesa and runs up and down the canyon (stops for breakfast at the cafe up there) and then back down the other side just outside gets to be about 15-20 people on avg ( slow group fast group etc)
