I can post a pic in the a.m. and is USF University of South Florida? I'm coming down in august for college in Boca is there anywhere to go wheeling?
Near Boca there is the Big Cypress National Preserve, which is a legitimate OHV place, one of the few in FL. Redneck Yacht Club is a private place really close to Boca, but they are only open like once a year. Also, North Port (aka Nopo) is well known for offroad areas.
There is no place sanctioned to offroad in Nopo, but the Yorkshire Street area (north side of i75 - NW corner along i75 is the part with most of the interesting stuff) is basically a gigantic offroad area. It used to be a really big offroad area, especially with ATV guys, but then city ordinances and what not... Anyway, ppl still go over there and offroad, but don't be too reckless and be very weary observing the speed limits and road laws anytime you're on pavement in the area (sometimes cops will snoop around there, but I've never seen them there personally - somebody died over there like last year b/c they weren't wearing a seatbelt and the truck rolled in during a turn - apparently cops cracked down soon after that, but I've been back once about 6 months ago and it was all clear. If you guys want to go to Yorkshire just PM me and I'd be happy to accompany you guys, but my availability is not so good, so no promises - sorry.
Big Cypress and Redneck Yacht club are your best bets though. And that Yorkshire area is always changing with the locals occasionally tearing it up - I got stuck in an turn-type area that I drove through fine previously, but then the next time I came some ATV types had roosted thru so much that I got high centered. I've also found shell casings out there, but most people are friendly and if you have an obvious 4x4 type vehicle they'll be happy to see you (cops might not when you're passing thru town, but yeah...).
Have fun.
