I loved Fright Fest at SFGrAdv! Awesome decorations, esp. the blood coloured fountains
Fantastic spooky parade and shows, brilliant atmospheric scare zones and night rides on Nightro
The only aspect that wasn't too great when I visited was the actual upcharge Haunts / mazes. They were just okay. But overall, I loved the event and would love to visit more SF fright fests at different SF parks.
