Looks like Sunday the 16th is the day. The tentative plan is this:
Start off in new Braunfels and rip up Hwy 46 to Spring Branch (there is a cool little FM Rd. off 46 to Spring Branch but I'll have to look up the #). Go up Hwy 281 a couple of miles and come back RR32 through Devils Back Bone to San Marcos. There is a picnic area in the middle of the BB we could stop at for some pics. Then end up at Grins for refreshments in San Marcos.

Opine?
