This is a "fun" thread to brainstorm about tweo-story pits ala professional trade shows, but alas it is NOT allowed by FIRST. Pits should be limited to 10' in height. Also, if you've never been to Atlanta GWCC, your pit should be open-topped to let-in as much of the ambient lighting as possible; otherwise makes it tough to work on robot!
Even if it was allowed, it is hugely cost-prohibited and the venue (The Georgia Dome and World Congress Center) imposes their own safety regulations:

Better start getting your funding, plans, permits, etc for the Taj Mahal ready for the 2008 season!
