This does not surprise me.
I was steelhead fishing in NY last year, and hooked a hot fish, which naturally ran down river, fast. I was quickly well into my backing while standing waist-deep in a strong current. Before long, the fisherman below me, whose casting I had been admiring for some time, stopped fishing, and proceeded up the bank to ask whether I needed a hand. I thanked him, and said that I was OK. He stayed 25 yards or so below me, ready to tail the fish, if I asked. I worked the fish into the soft water, and brought it to hand, without assistance. The fisherman walked up and congratulated me on a nice fish and a good job landing it. It was then that I recognized him as Travis Johnson, who I knew to be on the river. I was impressed that he came up to offer assistance, and then waited around just in case I changed my mind, or the current got the best of me, I assume. Anyway, he seemed like a genuinely nice guy, and boy, can he cast!
I can't understand why some folks think a drink can is harder to carry out when it is empty than it was to carry in when it was full.
