Expos are lots of fun! I used to go to the one in Brockton before they stopped and then moved to this new location. There are a ton of cool things to see, not just snakes and lizards. Plus you get to talk to people, get ideas, and see what's going on in the local community.
Only problem is that Expos are tempting! There have been more than a few times I didn't have a spare enclosure but started brainstorming how I could buy and keep some gorgeous creature I ran across! I planning on getting a few more additions next month, as long as Animal Plastics gets me my enclosures on time!
