Don't know if it's true but i think i read somewhere that they usually do not go more than 10-20 feet away from their enclosure if they get out.

Could be worse though, it could be someone else's snake that escaped. I was looking after a baby corn and he did a runner from a tub when i was cleaning the main tub. Pencil thin snake that could probably do 100m in about 9.65 sec! heading under carpet, possibly through floorboards under the house/next doors house! ...arhh panic!!! luckily i spotted he had gone early on and grabbed him just before he got too far.

Hope you find her!!

may be sit a tub on a heat mat with used rodent bedding in and get a smell going, and hide a F/T in there and set up a night watch and hope she goes in for a look, just an idea, probably i bad one
