20 / 25 years ago we used to hire a guide to fish the Manistee River in Michigan for steelhead in one of those flat bottom boats. The guide would maneuver it around with oars.It was pretty cool to see the current moving past the boat then look to shore and realize we weren't moving. Did that for 2 or 3 years until we were able to figure the river out for ourselves. Only having a weekend at a time it was money well spent
