I think Manhattan is a great place for a family. As you'd expect, the University is the life of the town. Understandable if KSU athletic games wouldn't really be your thing, but there are a lot of events/shows at McCain and art exhibits that roll through the beach museum. Outdoor concerts in city park are regular throughout the summer, the Symphony in the Flint Hills and Country Stampede (if those are your style) take place annually. Running/Hiking on the Konza Prairie is amazing, I really miss that. Also Pillsbury Crossing is a cool place in the summer to go.
