Bandera used to be pretty cool... been "absorbed" by San Antone. Years ago, used to have a cool city park-lake to camp at. Haven't been there for quite some time because of traffic and expansion of the "Greater San Antonio" area...
Sorry about the Scorpion bite in Blanco... scorpions here aren't serious. You DO, however, know you've been bitten. Hope you get a chance to check out Wimberley, Fredrickburg, Kerrville )home of the folk festival) & New Braunfels. Maybe even take in a show at Gruene Hall...
