Living in San Antonio....
About 11 years ago I lived in San Antonio for a spell. I passed the Alamo everyday to and fro work. Finally, on a day off, a friend and I decided to go in.
Words can not express my utter disappointment. It was completely empty save for a few flags! There was a little museum attached but the Alamo itself was barren. If I would have paid to go in, I would have been ubber p.o.'d.
The best part of the Alamo is the outside and the inner little courtyard area where this massive tree reigns supreme.
Last trip to San Antonio, as we were doing the downtown strip - Ripley's Believe It or Not, Palace of Wax, etc., we dropped in for the last 20 mins or so throught the courtyard so we didn't actually go into the Alamo itself. My son has expressed interest in going back for the entire "experience" of the Alamo so when we do the Mission Trails I guess we will see if it has improved.
