tdolloI'm always scared of getting my skis juked so i usually put one of my skis on a certain rack, and the other one on a separate rack, doesn't seem like much but if someone is gonna try and steal your skis they aren't gonna walk around with a single ski till they find the other one. They'll most likely just grab a pair that's together. Hope you find yours
This is the way to go if you don't have a lock. A lot of people also use the technique of putting one of their skis with one of their friend's skis to create a pair made of 2 separate skis. I would advise against this because thieves probably don't take the time to make sure that both of the skis are the same. If they see a ski that they like they probably assume that the other ski with it is a match and they snag it and gtfo. Then you and your friend are both left with just one ski.
To OP, I hope you see the thief on the mountain and get to confront him and get your skis back. One time I set my gloves and helmet down on the table while I was buying lunch. I came back to my table just in time to see my gloves being stolen. I yelled at him and he dropped the gloves. It was one of my shining moments as a skier and it would probably feel even better if you were reunited with a brand new pair of skis.
