Day At San Telmo Market

All the guidebooks say the Sunday street market in the San Telmo neighborhood is a must-see. Indeed, it was the largest market I have ever seen. It went down one street for 20-30 blocks, with many side streets full, as well.
Booths contained crafts, tango-themed everything, clothes, art, leather goods, and antiques. Cool stuff, but overwhelming. The 90 degree weather and 5 mile walk to get there wore me down, too.
San Telmo is an old neighborhood, with great European architecture and cobblestone streets.
