Visit any rural diner between 8:00 and 9:00 (or urban diner between 9:00 and 11:00) when it's otherwise quiet. I'll bet you will find a cluster or two of elderly people swapping lies.
Indoor malls used to be similar gathering places for people who wanted to walk without being in the weather.
Basically, look anywhere the 20- or 30-somethings aren't.
