LOTS of places to go 4wheeling around here. There is an offroad park in Azusa canyon (210w to Azusa Ave, then go north 8-9 miles to the ohv park). The Cajon pass has a few open dirt trails. Lytle Creek is a putt putt trail, but you can stop by the ranger station there and pick up an adventure pass and trail guide to what is open. From what I understand the San Suvaine trail (devistated by the wild fires 2 years ago) will reopen after Labor Day. Arrowhead, and Big Bear still have a lot of closed trails. Andy would be the one to answer those questions. I'm only off work 1 day a week so offroading has it's limits. GRRRRRRR
