if they are closed they wont have any rails, but that doesnt mean you couldnt build your own and set it up.
"YOU ARE THE BIGGEST STUPID, MOST NARROW-MINDED PERSON I HAVE EVER SEEN, NOT ONLY ARE YOU A COMPLETE JACKASS FUCKING IDIOT, YOU DESERVE TO BE PUNCHED IN THE FACE FOR WHAT YOU JUST WROTE, I SWEAR IF YOU WERE IN FRONT OF MY RIGHT NOW I WOULD PUNCH YOU IN THE FUCKING FACE THEN BEAT YOU WITH AN ALUMINUM BAT, AND SHOVE MY TENNIS RAQUET UP YOUR TIGHT ASSHOLE BECAUSE OF HOW IGNORANT YOU ARE"
I'm sure you will be able to set up a cooler park than the awful ones they had all season. Okemo parks have gone downhill big time. There is defiantly still snow by the pipe and all of the rails are outside the shack at the bottom of the pipe. Good luck, hope you don't get bitched out by the power tripping park crew tools.
