You should also consider Circle B (GCNKD9) and Gator Creek (GCNKD9) both are environmental lands properties and well maintained. The Upper Hillsborough is nice, very rustic, no hiking trails but no hunting there. If you are looking for numbers, check out the Easy series (GCNXV8)
1. Lake Parker eastern shore "power trail". Easy finds, good for the numbers
2. Lake Hollingsworth (my FIL walks it on occasion) A lot of people use this lake, not many caches to look for.
3. Lakeland Highland Scrub - looks interesting... Nice place, one of the higher points in Lakeland, think beach sand
4. Carter Park Trails - also looks inviting. Watch out for the mountain bikes, old phosphate pits, there is a night cache out there and a few caches.
Hope this helps.
