Dayton, Ohio offers an affordable, walkable small-city vibe with big-city amenities—rich aviation history (Wright Brothers sites and the National Museum of the U.S. Air Force), lively neighborhoods like the Oregon District, a growing craft-beer and restaurant scene, riverfront trails and strong university-driven arts and events—comfortable and interesting for multi-week contracts.
Within easy weekend reach are Cincinnati (~50 miles) and Columbus (~70 miles) for major sports, concerts and larger urban outings, so you get a relaxed home base plus big-city options.
