GM had set up "The Drive" a few months ago in Las Vegas. $10.00, a breathalizer test and a driver's license will give you a choice of 'off-roading' a new H2 or H3 on their Hummer Hill (a complete Hummer obstacle course) and a Tahoe Hill (similar to the Hummer hill, but on a smaller scale). A professional driver sits with you. Or, you can drive a choice of any other GM vehicle on their 'race track' to test it's performance. They encourage you to take them up to pretty high speeds to test performance (except the Hummer on the hill, of course). You get two drives .. can be one Hummer and one other non-Hummer, or, two other non-Hummers. I took the H2 and a Chevy SSR. I was there for their "Media Day" before the public had access. It was good for me at the time since I hadn't off-roaded mine yet.
