Mega Help for this weekend!

Seriously, what kind of wattage are you looking for?

I have 2 1600w UPSes that may do the trick if you aren't looking for terribly extended periods... if I can find them.

And to answer you Emily - yes.

Rob,

If you can find 1 that would be great. It's not going to be for a long time and one would do nicely.  On a side note, does anyone know if any of the pavillions at camp sac have outlets or are near any?

You are going to want a pavilion near a cabin in order to be near an outlet.  There is the one pavilion near/between the wagons and the Waterfront cabin.  At the bottom of the hill behind the Temple cabin there is a small pavilion ner there, I think.  You could run a line from there to the Temple cabin.

there is a tent pad right next to the Cabin of Spiders

If it's for a short time AND can be plugged into a cigerette lighter OR one of those round power plugs (like used for electic keyboards, and stuff), then you can use the battery pack my CPAP runs off of.  I have that with me every event.
