Don't ride when wet. See the website for trail closures.
I liked this trail the best of the four options. It is slightly longer but is a good mix of smooth packed dirt and roots. Some of the ruts have gotten a little deep and a new trail is being ridden in right next to them. You can get up some speed in a few places with enough incline to break a sweat. There is almost no traffic out there and just a good intermediate ride with three other trails in the same place.
