Well then guess you are set then permit wise. But i think a alpine coaster will be way easier. You could zig zag through the woods and don't come back up until the end because there will be a chain to pull you up to the house. So that was my idea!
Good luck to you, As many people have tried but failed because of building orders and they didn't brace it enough! So I will tell you now brace everything like three times, it is better safe than sorry!
Well since it is your first time I wouldn't be dissapointed neither will your cousins! It is a themeing wonderland. You can be as small as an ant and face a yeti all in one day!!! (I am going in april *sorry*) So have fun!
^ This may sound wierd but i though that ROTM was a simulater not a coaster and if it is a coaster can somone send me pics of the inside os a pov? there is no way of me riding it (to scared lol)!
