SST was originally built to avoid the sandy two-track that runs parallel to it. It exits, heading out, near that big open field - bordering that under the trees is a sensitive area they do not want bikes on, so it pops back out on the two-track to continue to the rest of the trails. Most people treat that as a warm up ride. Some find it a good opportunity to use their big ring.
Others use it as an opportunity to spy a bald eagle in the distance, or an assortment of other birds not often seen. Guess people just make it what is to them. Remember the days when there were no cell phones? Plan your excursions accordingly. Have tools on hand to do trail side repairs so your "limp" out is not so bad. I've been on some mountain trails ever so grateful no serious mechanical happened that would mean I would have to walk 10 or 12 miles back to the truck. If it did happen, I think I carry enough stuff to improvise a way to ride back in some fashion or another. If Balm-Boyette Nature Preserve was not a Nature Preserve we could set up the trails however we wish, but rulz are rulz.
So, treat the trails - two track connectors as well, which we have tried to keep to a minimum - as the whole trail system and enjoy that we get close to 25 miles of riding in the woods.
