I Rode Shark River one day and had some fun there too. It would be nice if they'd cut the weeds down on the one path that according to the Ranger "is on the map but not recognized as a trail"
Tatum kinda blows. not really "mountain biking"
but I still go there every few months for a change of pace. but I like 5 miles away. otherwise I would never bother.
I have been there a few times over the summer, Its a good place for a workout ride if you just want to repeat hills or work on cardio . Its also a great place for kids that are just starting out.
