Right on. I always liked the River-walk, too. Before I had kids, I was there for 2 weeks and I flew my wife out so that she’d be there Thursday night to Sunday night (the boss scheduled Friday’s activities to only last until noon). My wife really liked it, too. We liked going up in their version of the Space Needle and eating in their rotating restaurant.
If you go back to San Antonio, there is a mission south of town on the ‘Mission Trail’ that is very similar to The Alamo, complete with the surrounding wall that no longer exists at the downtown location. Gives a much better view of what the 184 men were tring to defend.
As an aside, I had a relative that died fighting for Texas’ freedom at The Alamo.
