It's a social club for the Philly upper class. It's a mix of old money, rich businesspeople, social climbers etc. Definitely an older crowd but they have been trying to get young blood in the place. I know a couple people who are on the younger side that are members, but unsurprisingly they have that 'I'm better than you attitude' that comes with being a member as much as the older members. Only reason worth joining is because they own 4 (?) very nice golf courses in the area
