Jeff--Friday night works fine too, if they are letting the public in.
Most of the teams are set up or almost ready, fires are just starting or about to get going. Coffee pots are hard to find, but a lot of the teams are "inbibing" fluids of unknown heritage
Overnight Friday and into the "wee hours" are when the teams do most of the internal visiting and such--great time normally while trying to stay awake
