A: Wow, you guys have a vibrant city center — and wind! I liked all the restaurants in Bricktown and visited Cattlemen’s Steakhouse in Stockyards City. The Oklahoma City National Memorial was striking and an important reminder of how we stand on a lot of people’s shoulders to enjoy the lives we do. Q: How are Main Streets changing across the country? A: There is a renewed emphasis on downtown because it is what gives each community its character. You don’t get that from a concrete, tilt-up big-box development. It’s no wonder the National Trust for Historic Preservation is behind the excellent Main Street program because America’s foundation for greatness has come from preserving the past. ... I teach that the key to any Main Street program is to remove the idea of "independent business” and understand it is "interdependent” businesses. Originally, Main Street had the saloon, the hotel, the livery, the general store, the church — all of the services — because they all needed each other.
