I am currently interested in planning a mountain biking camping trip and have found that locating the sort of trail I am looking for is very difficult. There will be a team of us going out, but the gist is not to go to a developed camp where we can ride different trails for a few days, but rather to be able to set loose in a national forest for about 2 days ride out, 2 days at or chosen camp location, and the ride back. We are all skilled riders and campers with great experience in wilderness/camping/etc situations, and therefore heavily developed trail isn't quite as necessary. I thought perhaps a very long back county horse trail may suffice, but I have been unsuccesful in locating something appropriate. We are willing to travel most anywhere in the US, but the closer to the southeast would be preferable. Any information someone could offer would be great. Thanks.
