I am gaining way in encouraging my man to build a rack. We have our snakes in tanks now, but we May be purchasing a property with a Very small house; there's no way we could fit our tanks and BPs in there, and any spare room would be needed for the water-filled fish tanks! Mark was pretty against racks/r-maids, saying they aren't good for display purposes, but I think the space saving properties are winning him over..
So, compare racks and r-maids to tanks... what's your preference?
