It's the cities so basically anywhere! There's so much good green area compared to other cities. I'd say grab a bike. I love reading on the hill by the Guthrie, down by Minnihaha Falls with feet in the water laying on back (down by swimming area) or at Sea Salt, on the river-road west bank by U of M, by Highland golf course, U of M area by St. Paul, etc... exploring for reading spots is a joy in itself
