I just recently moved to fullerton and want to do some mild offroading up here. I would always go to borrego springs when i lived in san diego. anything similair up here?
You can go up to Azusa Canyon OHV off 210 fwy and Azusa exit, but this is mainly for mudders. Best place I found that's relatively close is Cleghorn off the 15 fwy (about 50-60 miles away though). All others seem to be pretty far.
