I've been on two skycoasters at SFGAdv, and Royal Gorge National Park. SFGAdv had the taller skycoaster, but the one at Royal Gorge (Colorado) was smaller, but swung out over a canyon with a river more then 300 ft. down. That was scarier then any other coaster I've been on (so far anyways) and was worth the extra money.
The defunct Viper at SFGAdv was definitely the roughest and worst coaster I've ever been on. I got a nose bleed on that ride, and IDK if it was the skull smashing ride or my allergies, but the ride was awful.

I'm kind of new here, and hardly anyone I know likes Scream Machine like I do
