Marymac- you described some of the charm of the fest!   People do not camp because they expect the comforts of home.

I do agree with you, it is not my favorite fest, but Philly has its own charm and you cannot compare apples to oranges.   Philly should not be like Old Songs, nor vice versa. There is a distinct community who enjoys the event - and that includes more than just music. You mentioned drinking, and they do not sell alcohol on the premises, but I am sure it is readily available - however, I have not witnessed any incidents in all the years I've attended. The rush for "prime real estate" is tame - try getting a subway in NYC on a Monday morning and you will see controlled anarchy!   

It's not everyones cup of tea, but it has an ambiance that many people enjoy.
