Yes, I've been to Wharton State Forest. I actually went there about a week after I got my truck. The wheeling is relatively mild...many parts or more of a trail ride than off-roading. That said, there are some deep, soupy mud holes there if that's your thing. I would heavily suggest a winch if you're going alone. Your truck will get scraped-up because the trails were narrow and heavily wooded. Also, everything is sand, so your engine bay and undercarriage will get wicked nasty sand-cement all over - NOT easy to clean. If you couldn't tell, it was far from my cup of tea. I would heavily suggest sticking to Rausch Creek. The park is way nicer in every way. The only 'advantage' Wharton held was the price - free. This is just my .02, obviously.Btw, I'm not sure where you are in MD, but I am in the eastern WV pandhandle near Hagarstown. We ought to meet up sometime.
