Ok, so the other day I'm floating down the river and I get to the take out and there are 2 guys. One guy is holding the prettiest steelhead that I've ever seen, blue on the back and silver down the sides. This fish is unbelievably beautiful. The second guy holds a stringer of fish, most of them nice, but had obviously been in the water for awhile. So...how do you tell if a fish is a late summer fish or a winter fish?
