Me and my dad (age 73) went for the walking tour of Tijuana. At first I was a little hesitant, but Tadeo our guide was excellent and the trip was very well co-ordinated. We mostly walked along Avenida Revolucion to the arch, along the streets with musicians stopping by to enter the markets. We had enough time to shop in the candy stores and tne handicrafts.The restaurant selection was so good and so was the Tequila tasting. The only glitch I would say is the initial communication, this process can be initiated a bit ahead of meeting time to prevent any anxiety.
