Flickr is fun. I got an email from Dr. Biswas in India, who seems passionate about caves and the critters living in them. He liked several of my photos of Yucatan caves and asked if he could use them on his educational website. Anything for science!
I also got some emails from a Peruvian knife-maker who liked my photos of Mayan temples--he insists I should come to Lima and see some real ruins. Peru is one of the top three places on my shortlist of future travel destinations, but I'm a bit leery about meeting up with Walter.
