 This festival has been going on since 1970. It's kind of like Woodstock, so there are these generations and generations of fans. There's a kids' field with playgrounds, arts and crafts, face painting. There are diaper-changing areas. I mean, 50 years is such a long time for pop culture and music. I'm pretty sure there weren't diaper-changing areas at the beginning. What did it look like in the beginning? How has it changed over time?
