The biggest they had the last 2 years I have gone have been 4 person high speed quads.
Also I'll be there tomorrow if anyone wants to meet up to shred.
I rode the 6 chair this season actually. Its called the kaatskill flyer. On my first trip up, I got the idiot cord on my mitts entangled in the chair lol. I go to skate off and get yanked back to the chair. Luckily I was able to brace myself, and rip the freaking cord off with all of my might.
