Seems like the Boomerang coaster is closed often.. One of my friends went to the park this year and also said it was closed. Also, remember that incident from last summer when the restraints popped up open in the middle of the ride? http://www.themeparkreview.com/forum/viewtopic.php?f=2&t=56209
By the way, I really hate that SLC ride Ednor. I'm not a fan of Vekoma coasters.. but this ride is NOT smooth at all. Anyways, I remember not having fun riding it.
I like the Goliath. Not the best coaster ever, but airtime is fun and the view is nice!
