Nailed it. Most folks at the US Open are there for the booze and people watching. The few times I've gone, it seems like the actual tennis fans are few and far between. I compare that to Wimbledon where I was getting into conversations with folks constantly who were obvious tennis nerds. Tennis just isn't popular in the States anymore... with the exception of Florida and California.Open gets huge crowds of NYC folks and corporate tix, but most come for the atmosphere and to walk around outside during a nice warm day and know or care nothing about tennis.
