I've posted some pix of the fuel depot that I set up at Burning Flipside '08. This was a pretty successful design.

Not pictured are the puck lights on the back side used to illuminate the soaking tanks, or the warning posters on the front side. The barricade design is a simple variation on one used by Chad Bennet. This stood up in wind gusts up to 40 mph without being staked. It's a sheet of 1/2" plywood cut into two equal sections that taper from 4' wide at the bottom to 3' wide at the top, which are then hinged together. The cutouts for carrying handles should really be located lower, about halfway down.

Those soaking tanks are 6-gallon "oily waste cans." They're designed to be fire-resistant, and they worked: the fuel depot was downwind of the effigy and pyrotechnics on burn night, and embers fell directly on it without incident. The cans pictured are plastic; they're also available in metal, and that might be a better option, as the metal design looks like it would sit more stably on uneven ground, and could even be staked down if need be. The size of the cans means you can have a lot of people soaking their wicks simultaneously, which came in handy for the fire procession. The lids are self-closing. They don't make an airtight seal, and we probably lost some white gas to evaporation.
