I would not go wheeling anywhere around PV, the locals will call the law and you will lose your Jeep for a bit. That and it will cost you in tow fees. I know, I used to work for the tow company years ago!
You will need to find another place to go, like Big Bear, Gorman, the high desert, etc. Maybe Azusa Canyon? Don't know about that one but maybe someone will chime in.
