I mean, I have my list of both US and International coaster to-do's but that doesn't mean I'll be making my way to them anytime soon.
CoasterForce has a topic about this and I update it whenever I check one off, replacing it with a new one.... Since I'm pretty well traveled in the US, my domestic To-Do list is pretty random at this point, haha
A quick copy/paste has it as such -
Domestic -
1 VelociCoaster - Islands of Adventure
2 Monster - Adventureland
3 Jersey Devil - Six Flags Great Adventure (D'oh)
4 Emperor - SeaWorld San Diego
5 Cannibal - Lagoon (Round 2)
6 Steel Curtain - Kennywood (round 2?)
7 Iron Gwazi - Busch Gardens Tampa (lol)
8 Switchback - ZDT'S
9 Giant Dipper - Belmont Park (round 2)
10 Ice Breaker - SeaWorld Orlando (lol)
International -
1 Wildfire - Kolmården
2 Shambhala - PortAventura
3 Montezum - Hopi Hari
4 Anaconda - Gold Reef City
5 Scenic Railway - Luna Park (aus)
6 T Express - Everland
7 Steel Dragon 2000 - Nagashima Spa Land
8 Katun - Mirabilandia
9 Wood Coaster - Knight Valley
10 Twister - Gröna Lund - this one might actually happen next year if the park is allowed to open.
