Walkable neighborhoods in the U.S

We were in Dogpatch. I actually briefly attended SFSU many years ago, and have some familiairity from repeated trips, but that area as a neighborhood was new to me. We had our doubts! But we enjoyed it a lot as a neighborhood and found it a fun doable walk to downtown and fine in terms of grabbing a bus or streetcar to many other neighborhoods. We were probably the oldest “residents” during our 10 day stay as it seemed like there were so many younger singles and couples living in many small new apartments.
