Yes, Nationalmountainbike.com has lots of local traffic and rides posted all the time--and the trail info is there.
I think AEDC would be a good bet, minus scenery. You might get some nice shots down by the lake.
The full loop is 14 miles, not super tech and no major climbing, but a good ride. With a map it is very easy for a weaker rider to shortcut out when he/she has had enough. It's about as close as anything to M'boro.
Scenery can be had at Franklin/Marion State Forest, but it's a bit further away and I've not beeen there in a while, but it has new mileage, double but, i'm not sure how well it is marked.
Chickasaw Trace at Columbia is an hour or so away, nice trail, goes by the river, has shortcuts. About 8 miles of trail there.
