After my first time with Hare (when we hit a lot of dead ends) I got in with a group of Becky's Boyz that were riding at RAC most every Sunday. They had a local guy (Jeff) that was the ride leader who REALLY knew his way around. I sometimes had my GPS along recording the track.
At some point I took a bunch of my tracks and consolidated them into a single track that had many of the good trails on it. I've been a few times since without our guide but with my GPS and was generally able to find most of the GOOD stuff. (Although I have been known to ride my tracks in a smalish circle without realizing it

)
I still know one guy that rides there with Jeff most Sundays - except not when it's real cold or rainy etc. - that I will probably relink with this year.
(the rest of Becky's Boyz have gotten more into Trials now and don't go anymore)
Interest has recently also been expressed by a couple of other relatively new DAMN folks in tagging along next time I go.
The area I ride is along Valley Rd. between 901 and 61. The Freeride REALLY likes it there.
I've emailed with 2way2wheels and it appears he is a very knowledgeable regular there.
I'd be glad to share my tracks and between me and the others discussed above and my tracks I think we could solve the "where is the good riding" problem. Also in past years the ROOR enduro folks have cut (or re-cut) a bunch of GREAT single track there too.
