Looks like the ski swap at the NY State Fairgrounds will be happening again in 2018. I think the dates are Aug. 22 the Sept. 3 but not clear when people can buy stuff. I stopped by 5-6 years ago on the way to Lake Placid in early Sept. Wasn't looking at the used skis that much, but there was a lot of stuff in general.
