With input from some of the active wheelers, I'm making a couple Big Dogs events official DEJA trail rides. The first is their Spring Fling run. You can pre-register on their website. http://www.bigdogsoffroad.com/?q=node/15 The event fees are $78/person for the weekend and $35 if you wish to camp. More info will be posted after Big Dogs updates their site (link above).
Yes, this is the same weekend as GWNF, but I don't believe the people who went last year went to GWNF. You get to camp at either place. If you're up in the air about which to goto, pick GWNF. It's a bit more hustic (redneck?) at Big Dogs, the trails are a lot harder too.
