Last week, I was in Colorado for ski trip. I also wanted to fish, so I hired a trout guide for a day. He told me that the week before, he had taken out a guy and his daughter (8 or 9 years old.) I think it was her first time ever. Anyway, air temps were around 5 degrees, water was in the low 30's. After about an hour, the little girl said, "Is it always like this?" Then, she went and sat in the car the rest of the day. She may never fish again.
