Factore, I also live in NW Hillsborough (carrollwood) and agree, there isn't much in our neck o' the woods. Luckily it's just down Fletcher to WTA parks. I did find a decent little place to get miles in, Lake Rogers Park. It's located about 1,000 yards W of Gunn on N. Mobley, past Fox's corner. It's a 2 mile off-road single track loop with a couple dips, some sand (ugh) and lots of mulch, which isn't much better than sand sometimes. There are also some side or spur trails that remind me of Panther (roots) or the center of Flatwoods. A pretty little park with a couple cool lakes, if you're an angler. If you don't have the time to get to the other parks but need to put some miles in, it does suffice, for me at least.
