In my experience, taking someone who is afraid or doesn't like snakes to a reptile expo is a terrible idea! I brought my boyfriend to the expo in Hamburg and he had an anxiety attack and was severely traumatized by the whole thing. People have large snakes wrapped around their bodies walking around, and while that may seem cool to you or me, it can be absolutely terrifying to some one who is uncomfortable around these animals. I would start her off somewhere more controlled, where she can look at one without having to worry about a crowd and loose snakes not to mention other reptiles and amphibians that may make her nervous (there were crocs at the last one if I remember correctly). Maybe go to a friends house who has a nice, docile snake, or a pet store that will let you hold a ball.
