Just returned from a 3 week trip to Mexico City and Cuernavaca. I decided to take my 4X5, and am pleased that I did. I had no problems and the people I encountered as they couldn't have been nicer. It was also interesting to see the same photography group continues to exist on Calle Hamburgo, Club Fotografico de Mexico, where I rented darkrooms 35 years ago. Also noteworthy was one of the club founders, Enrique Segarra (age 86) was exhibiting his work in the Sullivan Sunday art fair. His work was historically significant I think, with fotos of Diego Rivera, and Mexican life 50-60 years ago. I really liked many of his fotos, alas they were all framed, or I would have bought one.
