Practice in Camp Driveway or your favorite park first. See if you can live on "just what you brung."
Then find a piece of private property or a park that allows camping, but has no hook ups.
After 3 or 4 tries you'll figure out what you need, don't need, can live without and the stuff you absolutely CAN'T live without.
