A couple of us are doing the Get-A-Way Tour out of Clarksville, TX in June.  http://redrivercoc.com/2010/12/31/bicycling-spring-gateway-to-texas-getoaoway-to ur/
 
It sounds like a good time and is from what I have heard from those who have done it.  Basically 3 full days of riding all starting and ending in Clarksville, TX.  You pick your distance each day.  They provide sag, rest stops when C-Stores are too far apart and indoor camping (with a/c!!!!!).
 
It is time now to plan your summer vacation so come out with us and have a good time!  It would be fun to have a bunch of RBENTer's along.
