I most often camp. I usually hand wash in a sink at the campground, or sometimes a gas station etc. Instead of a stopper, I put the clothes in a plastic bag from a convenience store. I put the bag in the sink and fill it up with water and sometimes add a little soap. The sinks are often not very clean, so I prefer using a plastic bag. It also gives me a way to carry the clothes out without getting the floor soaking wet for everyone else...

I will only rarely take the time to use washing machines and dryers, maybe once on a 2 week trip.

I carry a light weight line and use paper clips for clothes pins. Very lite, and I've found much more effective at drying than draping over the picnic table.
