Not sure what the weather will be like - it could be freezing one night and ~70°F the next afternoon, or where you're looking to go.

I've never ridden these routes but was looking forward to it once I got my bike and body squared away.

There are 22 routes just south of Hattiesburg, MS around Camp Shelby.

These routes were part of the MS Gravel Cup.

Sorry, but I can't post urls...
