Jack Brooks is an extremely well maintained, heart-pounding, good time. 6.5 miles of roots, drops, quick climbs, and fast turns. Definitely NOT a "beginner" trail - the first 0.5 mile can be brutal, as can other sections. Trails are one-way, and a large map is posted at the trail-head. There are multiple TTF's that include teeters, large wooden burms, and roll-ins. Mosquitoes are typically pretty thick, and if you're the first one through in the morning, be prepared to meet the spiders.
