My brother rides it every day and he has seen a bunch of big black snakes. Watch out for the orange Giant bike, he is goofy. At the light, take a right and then an immediate left before the elementary school. Follow the road all the way down until in dead ends at a trail head. We haven't been riding long but were are testing all of the trails to find the best workout.
Some places can be a bit flat and windy but there are some excellent downhills and rocky climbs.
There is nothing advanced here that I saw. Knob Hill, is a swamp for 8 months out of the year. Boulder Park and L.B. Houston, where you'll get mugged and your bike stolen. Sister Grove, which is out in the middle of nowhere and is basically flat and eroided away. Its probably the trail I ride the most.
