Post more pics for sure. Ask around, go door to door. Somebody saw something, I guarantee it, you just have to find that person. Literally hand out out flyers in your neighborhood, knock on doors. The longer you wait the colder the trail gets.
And I guess we all have something to learn. Have pics handy of your skis and parts, so if god forbid this happens to you, you have something to give to the police etc.
Sorry your stuff got stolen man. Its a PITA, but I take my skis off my trailer and keep them in the locked garage just for this reason.
