Yes, and I don't get it. A small minority of people actually have a need to take stuff on the hill, otherwise it's asinine...
reasons TO carry a backpack:
- you have a DSLR in there and plan to use it
- you are doing a warmup run or two before head to lift accessible B/C
- that's about all I can think of... anything else should be able to stay in your car or the lodge
What made it worse was the fact that they kept falling down.
I'd guess that the backpack kinda throws you off your balance.
