I dunno. Maybe I'm just a JP fanboy, but I LOVE River Adventure. Like a lot. When the doors open and the music kicks in, I get goosebumps.
Now, it definitely needs an update. I'm not going to fight you on that one. But I love that ride. And I'd say JP is tied with Seuss for the second best themed land in the park.
I hope the land is expanded as rumors say, though. Camp Jurassic is great, but the land needs more than RA and CJ.
