That happened to me too back in 2006 while fishing the Vedder. It was mid January and an unsuspected down fall hit mid river where I got stuck in a snow bank. I was by myself and couldn't push my car while trying to turn my steering wheel and I would say a dozen fishers passed by (4 of them walking out of the bush getting ready to leave)...Not one offered to help even after I pleaded with them. Luckily an older gentleman driving home from work noticed me struggling, pulled over and steered my car while I pushed it out of the snow. He couldn't believe the disregard of people saying that 40 years ago it would have been unthinkable not to help a fellow human being.
I guess times have changed and I feel bad that you went through that...I definitely would have helped.
