Some years ago, wife and I went to see my oldest buddy from HS yet, he and I had gone to Fort Worth Tejas in '70, after his Navy term on the Med Cruise was over.....so we/wives took off for San Antonio.....make damn sure you walk the loop of the River Walk, and maybe stay at one of the hotels along the route, Alamo is easy walk distance from it......River Walk has lots of fun/interesting/cool places, well worth the stroll....takes about a day.....
Wife and I have a large pix of one of the stone bridges over the River, a purrfect pix showing much character of the place......in fact I spotted a very similar shot being sold on the .net by some other photographer......
