I know these canyons well, but have stayed away since last summer, three speeding tickets in 14 months...all on my motorcycle, never in my cars. The sweepers are so fast, but there is ALWAYS the MAN up there on weekends. I finally learned to wait for another pack of bikes or tuner cars to go up into the canyon, like maybe 5 minutes ahead of me, and it is ususlly then that one or more in that group is pulled over getting the ticket, and then I can just cruise, (speed) by. Do you guys just cruise in a pack at or under the speed limit? I think my last ticket was like doing 15 over the limit, I told the officer if I would have been going any slower I would tip over in the turn. Anyway I now ride, or take the Xfire up to Azusa canyon, over to Glendora ridge, if you go during the week, like after work, you see no one! Very nice, but kinda scary if you happen to crash or breakdown, because no one is there to help.
