I don't think you can have a better tailgate party toy than the Hummer grill. Sure, there have been plenty of barbecue designs in the past shaped like cars, but this one looks like it could withstand a firing range and I bet the fuel economy is a whole lot better than the real thing.
Probably the coolest feature about the Hummer grill is that it can mount right on the rear of your vehicle which makes for extremely easy carriage. The fact it folds up into the size of a tool box doesn't hurt things either. Forget about going green, the only color you'll be seeing this summer is red.
