Tip: Reserve early. Haha, I found out the hard way there are few NP campground close by for RV's. $31 isn't the problem finding a none reserved one is. I 90+% boonie camp and not liking what I'm seeing on Google Earth. my only experience with attending Jeep Jamboree's have been in Wyoming and Arizonia and finding camp near those events was easy. I should have know with this event being in SoCal and all.
