I've done the laundromat thing before. I was lucky enough to find what I called the "never ending dryer". I put a quarter in and it ran for almost an hour!
Although it's nice to get all the laundry done at one time, it's a pain to haul it to the laundromat, remember the detergent, fabric softener, etc and be patient while it's washing/drying.
A washer/dryer is something I hope never to have to go without again!
That was nice of you to offer your washer/dryer to Ranger. I would love to see the look on the Border Controller's face also! :D
