Personally, I like the freedom of the bar up, and having an un-obstructed view of the mountain. I don't use it to rest my arms on either. It's my choice and there aren't any written rules saying I need to put it down.
For those who don't know, Grouse has gone nuts trying to enforce the safety bar. They yell repeatedly now when you don't put it down. I mean they really scream. Friday the lifties at the bottom called the top and the top lifties threatened to get ski patrol to deal with us if we didn't put the bar down the next time. They screamed at my buddy and I on the baby chair, the one that goes maximum of 15 feet above the ground and slow as a slug. I was nearly above the road on Olympic and I heard some crazy liftie yelling about the bar.
This is kinda like the final straw for that place. Too many dumb issues, shitty vibes from everyone but the skiers, and greedy management.
Baker doesn't even have safety bars on their chairs, and they're an american resort. I'll see you peeps at Seymour next season.
