how do I wash dishes at a camp site?

[A]:
First, take your 5-gallon water jug and place it on the end of the picnic table. Now, put your wash basin on the bench seat below the spigot, for easy water access. Place your dish soap next to the water jug, and your dry dish towels, and sponges, too. If you have a drying rack, now is the time to set that up as well, but a beach towel stretched out on the other end of the picnic table will work just fine too. Really, it's your choice.
