lol college i hear ya, i'm a third year up in Davis and the only problem i've had is sometimes finding landlaords that won't flip out when they hear i have a "giant" lizard. The whole room thing would be nice for a tegu but if you check out the site thetegu.com you'll notice alot of people actully biuld nice enclosures for their tegu... i'd post pictures of mine but i left the software to my dig at home over winter brake. Now im not saying getting a tegu now would be easy... or practical and sometimes I think a back yard would make it easier, which i get my wish next year when i move into a house.
