This takes a brief history lesson. In late 73 OPEC turned off the oil and Nixon mandated the 55mph national speed limit. Before that Nevada didn't have one offically. The law was safe and sane. Street racers from 100s of miles away would decend on Freemont street, downtown Vegas. The NHP would look the other way as long as we kept our grudge matches north of town on the highway to Salt Lake. never tell her dad 'were going to Vegas!'
