OK, fantasy time....TOTALLY off the top of my head here...what woul dit cost to goto Kilt Camp if there was one within a 6-hour drive of the San Francisco Bay Area.

Transportation to and from...uh...a tank of gas: $30
Two nights, oh, heck...make it three, in the hotel.... $300
Three days grub...@$25/day...$75
Beer at the pub, three nights worth... $300 (or thereabouts, har!)
2.5 yards poly-viscose tartan... $65

or

2.5 yards wool from The Scottish Weaver... $100

assorted junk...$20

OK, so I could do this for $500- $600, which is one EXPENSIVE kilt, but it would sure be fun.
