Of course, if you don't mind cleaning your bike after, do Mike's route. I definitely agree with him that it's a very stimulating ride during the night. You can also make some pretty cool home videos here. Right in my backyard it's not so much a mtb trail but an all purpose dirt trail. No long climbs, but a lot of steep, technical ones.
Downhills are short but steep.
Roots, rocks and even a launching pad to get some big air. There are not a lot of trail users - sometime me and my dog are the only souls there. A lot of flat rutted fireroad.
