Having just left the U.P. it wouldn't be on my top 10 places to go for a duck trip, but I know it has a few bright spots. I'd be interested in spending a season on the east end to see what that's like.
As for MacQuarrie's old haunts, I don't believe they are very good anymore. They may have their occasional pushes of birds, but by and large, MN, WI, and the UP have lost their glory with the lack of bluebills. It would still be fun to check out the locations just for kicks, but when MacQuarrie lived, there were very few cottages in the area. Now the whole area is built up - every inch of shoreline, and much of the forest has been carved up into 40s and whatnot.
MacQuarrie's biography is just as good as his writings.
Nobody writes like MacQuarrie. I was set in my ways long before I read his books, and they are right up my alley.
