If I had ANY way of recording it, I would do it in a heartbeat. But I just don't know how to a) drag my car into my bedroom where the computer is or b) drag the computer out to the car, where the exhaust is.

I guess I need to find a way to record it with some small tape player and then record THAT using the computer mic. The quality won't be ideal, but it will work.

I'll give it a try and let you know if it works out. Any other methods are appreciated.
