We stopped in Grand Forks for lunch. Grand Forks is just over the border into North Dakota and the state border follows the river. We saw a large green space along the river and figured it was probably a good park for lunch. It was in the sense it was basically empty…including empty of amenities like bathrooms or a trash can! C’mon North Dakota! There was also green space on the Minnesota side of the river that we suspect was more developed / user-friendly. But we had a lunch on our picnic blanket. We got a kids meal grilled cheese from a sandwich shop for the kids. It came with milk, which turned out to be chocolate milk! Oscar and Delilah passed that milk box back and forth to the bitter end. After lunch, we explored a part of the river bank that was current dry. The mud had hardened into crunchy blocks. Oscar jumped on them to watch them crack and shatter.
