I kayaked the Blanco near Wimberley and there was no one around so I decided I wouldn't bother anyone if I had one of my hand rolled cigarettes...Yes perfectly legal tobacco/herbal blend. Well about two puffs in a rabid old man comes charging down the river telling me the law is on the way how dare I come to his back yard to partake in "illegal" past times. Apparently he watched me roll the thing through binoculars on his back patio. Sure enough when I took my boat out county PD was waiting. I showed them what I had and they were real cool and let me go on with my business.
