I was also there on Saturday and was anticipating it to be busy, being it's still spring break and the last weekend of the Boysenberry Festival (which they didn't expand this year I guess?)
Anyway, it was way busier than I expected. Maybe it was just me, but it was almost claustrophobically busy around Ghost Town. Essentially we did a lap around the park, watched Brother Yusef for a bit (excellent!), and bailed. It was just too much. Next year I'll try to go to the festival on a weekday.
