I particularly love the ball python community. That being said, most people who own ball pythons also own other species. It is like the gateway drug to reptiles.
I think it really just comes down to being animal lovers. I have had animals my whole life and I couldn't imagine a day without them. They are part of who I am. I love hanging out with my fellow reptile enthusiasts, and really anyone who loves animals. You can't come to my house if you don't love them! The cat and the dog are attention whores and they won't leave you alone until you pet them.
I consider life without animals to be lacking...and somewhat boring. I love going to reptile shows and I try to go as often as I can. Even if it is just to look around. I like the people too! I love to meet new reptile people and talk about them. Most of my family thinks I am crazy...so its nice to have people to relate to.
