The Alamo is open. Also walk over to the Menger, and look at the Teddy Roosevelt stuff in the hallway by the bar. Look for bullet holes in the bar and up on the wall. Mi Tierra is great, but always crowded.
East of SA is San Marcos: go to the Airport there, and look for the Commemorative Air Force base. “That’s All, Brother” is based there, and is the fully restored C-47 (and flying), that was plane number 1 in the D Day Invasion. Ask for Terry, tell him I sent you. Nice museum. Buzzie’s Barbecue in Kerrville tx is outstanding. Stay off the Riverwalk. It’s a waste of energy. If you do the Alamo, be sure to get directions to the Cathedral, as that is where Juan Seguin collected Alamo Defender’s remains, and stashed them. They were later placed in a sarcophagus, in the entrance to the Church. Across the street in the County Courthouse, is a collection of Spanish archives and memorabilia. Lots of history from before there was even a British Colony in New England.
