Ok, I just got back from taking a *walk*
over to the pits area Harvey mentioned, and all I can say is "wow". There is some seriously premium mountain biking terrain back there. I saw where a lot of the trails previously ran -- even though there is a lot of debris and downed trees, you can really get a feel for how good some of that stuff was. Seems to have had all kinds of stuff, from intermediate on the technical difficulty scale, all the way up to double diamond pucker-fest downhill stuff.
Garry: just a thought here, and it's probably a dumb one, but what are the chances of bartering with the DOF and giving up some of the already-shredded red/blue trails to the enduro boys in exchange for being allowed to build out this pits area into a mtb only area? Croom could use a few more technical areas, and there are probably spots on the reds/blues (south side maybe?) that are close to the sanctioned ATV areas that might be an attractive trade-off.
Sorry in advance for the probably excessive and un-warranted enthusiasm, but after seeing the possibilities in that pits area I figured I'd at least throw out the idea...
