I live close to 3 good trout streams but spend most of my time float fishing for smallies. I love trout fishing but our smallie fishing is much better than our trout fishing.
End of May is not the best time of year for smallmouth bass but if ya want to fish for smallies, I would also recommend Kip Vieth (Wildwood Float Trips). He is a great guy and knows the mississippi and St. Croix like the back of his hand. He'll take ya out in a drift boat and get you onto some big smallies.
Have fun!
