To each his own. My preference is coin-op laundry or campground/motel washing machine (if I happen to be in one that has that as an option.) The few times I've tried to wash my own and hang them to dry have never been successful. I find a drier is the only reasonable option. I'm never in any place during the warmest part of the day long enough to hang dry hand-wrung clothes sufficiently to then be able to pack them away without fear of fermentation.
