We where at a series of trails that we like to call "606." It is near Dulles Airport, not too far from rt 28. I have still not explored the whole trail system. We have uncovered about 15 miles of trails so far. It is always muddy, literaly, always. I try to go there only if it hasn't rained in a while. thier are lots of hill climbs and trenchs. One word of advice, always probe the trenchs. Everytime i gone there someone has got stuck. Before any of us had a winch last year i had to leave my X there over night in a sink hole. Didnt go over well with the parents:

"What do u mean u can't get it out...."
"We can, i just need a back-hoe or something like that..."

If you what directions or something like that just shoot me a PM.
