I asked this over at the Strike Point, but nobody answered so I'll repeat it here (where all the REAL experts are

Can anyone tell me how many different strikes there are in the McCarran (Las Vegas) Aiport set? I don't collect strikes, but played the machine after leaving the Tropicana and won 3 of them. They were all different, which led me to believe there must be more in the group. Oh, oh, have I just taken the fateful first step towards being a ss collector? Thanks for any help.
