Anyone ever try out these OHV parks? The parks are between the 10 FWY and 40 FWY at the Arizona border near a town called Parker, AZ on the river. I scouted out the OHV areas on my way back from a weekend of riding near the Laughlin strip and stopped by the staging areas to check it out, I noticed the trail maps that were posted on the bulletin board there and the "open areas" were no more than a 5 mile radius with the trails running off the map. It was such a nice little town (w/ casino) but it would be a shame to trailer all the bikes out there only to find out the riding area is very limited. Copper Basin Dunes from the side of the road looked very small and looked like one would need to take dirt tires as i only saw a couple of small dunes with lots of hard packed trails surrounding. I appericate any info, thanks.
