When I first got my BP, my wife put her on the dash board and she crawled in between the window and the dash and went behind the dash and I had to pull off the dash to get her out. But obviously if you take any snake into 30 degree weather they are going to go where it is warm and that is near the heater and the engine. I hope your RTB is alright. Personally I had to poke my with sticks at the worst angles to get her out. Most cars the RTB wont be able to go any where except inside the dash on top of things like your vents and steering column and cd player. So eventually you would think that it would crawl out on its own. Sorry to hear this and I hope everything went well and you knew the RTB couldnt get into the engine so you should have drove the car with the RTB in it to a garage or someplace warm until you got it out. Obviously its too late for this post, but for future reference I guess.
