Corsicana offers a cozy, affordable small-city feel with a walkable historic downtown, the Pearce Museum, the famed Collin Street Bakery, regular local events, nearby parks and lakes, and enough cafés and cultural spots to make multi-week stays pleasant and interesting.
Bigger-city options are close by — the Dallas–Fort Worth area is about 50–55 miles north and Waco roughly the same distance southwest, both an easy hour or so for weekend nightlife, major museums, or airport access.
