Are these [b]special[/b] tables and chairs that you want to bring? Are they hand painted works of art you want to show off?
If not, I would consider leaving them at home in Iowa and picking some furniture up from Freecycle in Salt Lake City or something.
You might want to consider some of this 'Playatech' furniture as well.
All of this furniture on that page is made out of pieces of plywood, which slots together to assemble, then disassembles to stack flat. No screws needed. Minimal space.
All you would need to make Playatech furniture would be plywood, a jigsaw, a drill, a pencil, an electrical outlet, and a measuring tape. A sawhorse might come in handy, too.
You might save a little on shipping costs if you bought the plywood closer to BRC, such as in Reno. Maybe you can cut the plywood into shape from the tailgate of your pick-up, who knows?
If you are really in a pinch, some lumber stores will even make the cuts in the plywood for you. Sometimes they charge, sometimes they don't. If they do charge, it's usually a dollar a cut.
You'd still have to make all of the cuts, so you should make a few of them at home to see how hard it is, and how long it takes.
When it comes time to pack up your camp, you can either donate all of your playaware furniture to families in need on the way out, or simply burn it all. No need to haul it all back home again.
