Actually the best fur is in the spring as long as they haven't started rubbing. I prefer the fall; in the spring the bugs and ticks are TERRIBLE. We went one spring and had to duct tape our sleeves and pantlegs. Black flies were in your face so bad you ate them with your lunch. Ticks everywhere. Never again. In the fall a few mosquitos is all you have to deal with. My experience is Canada and N. MN.
