Christmas DAY RIDE.... show off your gifts - 15-17 mph pace to San Marcos

Hey, Who wants to show off their new XMAS gifts?? I was thinking of heading south to Buda, Slaughter to Brodie to Manchacha to 1626 to twin creeks to old san antonio to buda. I will Provide a map at a later date, but distance of at least 50 miles... wondering how many might like 75 miles??
