I agree that Timberline is that resort where the lifties are so friendly. Unfortunately, I had a bad experience today. I've been a pass holder for at least 20 years, making it all the way to 70 years old, yahoo, discounted pass. It was more than epic mid November, first time up, when I had difficulty showing my pass that was under my edge of my coat where it was built in by the manufacturer. I've always been able to hold it up to present it. Being the first time up, I forgot the sequence. The scanner didn't like where it was and started to berate me and tell me I should put it on leash or get one of those old school there are those old school snap back pullout pass holders. I had two of those on my visible on my coat, but one was for my squeegee, the other to scrape ice out of my bindings. It kind of put a bad taste in my mouth. Then the second time around same attitude. I told my ski partner I was going to leave, but he talked me out of it. I'm sure glad he did because the 17" of snow really was epic!
