This question has been asked a lot...and I STILL don't have an answer for it! Personally, I love so many different snakes, I could never pick a favorite. When I'm in a position in life to start building my collection, I will most likely focus on bp's for breeding...but hope to have a wide variety of species for pets. And even many species I would never keep as pets, I would still want to list among "favorites"....I'll never have an answer for this question!
