Works for me!
As for where... The hardest part is digging the pit in our wonderful Colorado moraine, but I can get Brandon (march2304) to bring his shovel and we'll be golden
Off the top of my head I would look at the following areas:
Central Rockies around Aspen
Central Valley around Buena Vista
Western Slope around Ouray
All of those would have enough trails for three days and lots of variety for varying skill levels and several of us are familiar with the area(s)

This would also be a great opportunity to make a dry run for WFTW.
