Most of the lifts at my local don't have the vertical scrotum smashers or footrests, so I never quite understood why people wouldn't use the bar. I find it pretty comfortable to have the bar to lean and rest against. When I did go on a lift with the bars and footrests, it was a pain - my lower legs are apparently pretty long, so getting the board on the footrest is awkward, but not quite long enough that I'm comfortable dangling underneath.
Weirdly, I've had a couple moments this year (with the bar up) where I suddenly get very nervous about the height. I was never really afraid of heights and never had a problem on the chairlift anywhere before.. Not sure what that's about, but either way, having the bar down seems to stop that fear from creeping in, so I'm always kinda glad when the chair mates bring it down. As long as they don't bash me in the back of the head.
