We only did the trail one way... from Cisco Grove to Meadow Lake. We staged an elaborate shuttle system by taking Chris' truck and ATV trailer out and dropping it at Meadow Lake the day before (which took forever on the crappy dirt roads -- if we did that again we'd park farther back at Webber Lake). Then the next day we took my truck and ATV trailer and drove it out to Cisco Grove. We rode the trail, then loaded up on his truck and trailer and drove back around to pick up my truck and trailer. Took all freakin' day... about 10 hours to do just the trail itself one-way.
Fordyce is WORK on an ATV. Definitely the most difficult trail I've ever done, and that includes some of the toughest trails in Moab and the Rubicon (which is cake my comparison).
I might be interested in running it in the opposite direction, but there's supposedly only one month of the year when the water in the streams is low enough to get an ATV through, and that's October. If you wanna run it that way, lemme know and maybe we can get a small group together. I'm sure Chris would be up for that.
Right now I'm trying to put a small group together for a midweek Rubicon Trail ride in early-mid October. With the way the weather has been lately (especially the snow over the weekend) I'm hesitant to try to plan something past mid-Oct. The idea of getting stranded at 7000+' out there on an ATV in a snowstorm is intimidating. We wouldn't get the quads out until Spring!
