Nellis' BX is a "B" store. It does have a lot, but there are a few larger ones. The BX started selling guns about 3 years ago, that's the biggest change. The class 6 store is definitely cheaper than buying downtown, but they don't have a large selection of different brands of alcohol. As far as off-road stores, there are a couple, but they are rather small. One is Custom Trucks on Boulder Highway, and 4 Wheel Parts at Tropicana and Decatur, on the northeast corner. As far as Jeep rentals, I don't know if Hertz rents them, but there are other places that do. By the way, it's supposed to be a little cool, with temps in the 70s for today and tomorrow, but back up to the 90s by the end of the week.
