We fished small larger Prince nymphs with Sow Bug droppers all day and were consistently hooking up. The creek was very different than any Western stream; there is something about walking through farmland and staring at beautiful trout in a place you never would have imagined could hold fish. There was snow everywhere and not an inch of shelf ice; spring creeks in the winter are something special.
The "Driftless Area" is a really magical place to fish. The spring creeks reminded me of those in Montana and Wyoming. So, if you ever make it to the Midwest, and your not fishing warm water or the Lake Michigan tributaries, take a trip to the "Driftless Area" and you will not be disappointed.
