You really only have to keep your eyes open for water cuts and runoff trenches that haven't been filled. For trail riding I use a hardtail with or without suspension fork and Kenda Kosmic Light II tires in a 2.0 size to ride on top of the gravel, limestone or dirt. That tire will allow you to get off the trail and do a bit of asphault riding if you wish. It's not enough for loose sand or deep dirt however as it starts to spin without traction if your going uphill.
A lot of the TCC folks ride cross bikes on some of those trails. That suggests to me that they are sticking to the trails although I must admit I know little about cyclocross.
