Not being local, the difference between The Bullring, Las Vegas Speedway and Las Vegas Speedway wasn't obvious. The Bullring is a small circuit not much larger than an average motorway junction roundabout, so it wasn't quite the NASCAR experience we were expecting. that said it was a fairly enjoyable evening including lots of junior/mini's events as well as senior races. It is extremely stop/start and often takes 15/20mins to get going again.
The big downside of the evening was being stiffed for drinks by a snot nosed kid who swore blind to her manager that she'd served us even though we were stood there empty handed! Her manager backed her up and cut us off for the rest of the evening! Lesson to be learned, if you're coming in from the UK make sure everyone in your party has photo ID on them. They were far to strict on the number of drinks that can be served per person (2).
