Yikes... so you're saying you're not allowed to have pets on your property, and yet you have a large snake? If you get caught, you could lose your home, and your roomates might lose theirs too...
But anyways... mabye you could explain to a friend that your snake needs some fresh air, and they might let it crawl around on THEIR lawn. Good luck though, and I hope you have friends who like snakes. ~TR~
