Alan seconds the idea of Gary's cruise with a minor modification.
Stay in Fredericksburg, cruise 16 thru Kerrville to Medina. 337 to Vanderpool. (potential photo ops at Lost Maples state park) then up 187 to 39 and back to Kerrville.
He used to have a deer lease down there and says 39 and 337 are beautiful drives.
