It seems that the trailer park located 2067 N Las Vegas Blvd still exists. Their phone number is (702) 642-2323.

Although I couldn't find any evidence of the Pair A Dice Club, I think Las Vegas Blvd North and Main Street North are interchangeable names, because the Main St becomes Las Vegas Blvd north of Owens Ave and continue to use the numbers of Main St.

Further I have noticed that the Club on Hwy 91 was called Pair O Dice and the one from the matchbook Pair A Dice so that there is even a difference in the name.

Anyway, I would be interested in any fact about that club too, since the word "dice" always catch my interest ...
