Maybe I should consider that route. I was going to build large wooden display type enclosures, 2x2x6 for each of mine. If I went rack instead, I would have more room and money for more snakes and snake food :] I must admit though, I really love being able to sit here in my recliner and watch them. I know I could still see them in the tubs, but not as well, and wouldn't get to watch them "exploring"
