Prowling around my recent circuit, there are some gains in most places: New Orleans, Phoenix, Tampa, San Diego, and Palm Desert. Nothing in Flagstaff and while Yuma is flat, an hour west El Centro has five where historically there was one. My sense is that there was been a focus on small regional chains, but my sampling is too small to have any meaningful insight.
Well, so much for trying to get down to the 170's.
