Not sure where this should go, but it really only affects skaters, so I'm putting it here. Moderators, please move or repost on anther forum for a wider audience, as you see fit.
An adult skater I know showed up with new skates today and told me why. She was flying from NY to FL, and thought she could carry her skates on. The line for the security checkpoint was 2 hrs long, and when she got to the front, they said the blades were sharp and she couldn't carry them on. They then took the skates and threw them out right before her eyes! Luckily, they were not expensive skates/blades, but even so! Since many of us fly with skates, I thought I should remind us all that the TSA is capricious, and you risk your skates if you try to carry them on.
