I'm not saying your trails are boring that sounds pretty fun.

For what I'm riding, imagine 600-2000 ft inclines and declines throughout the trail (total elevation change) (some sharp, some not) with windy 1.5 foot wide trails. now imagine it full of dirt. now take a football field worth of rocks that range in sizes from golf balls to 60" televisions, and dump them on the trail. ensure they're really lose. that's the best description I can give you I guess.
