You can list members by location but it's a bit dysfunctional because it lists by town, then state if they put a city in.
To do it click the 'members' tab in the upper right corner.
Then at the bottom of the members list click the drop down for 'sort by' and select 'location' and list it 'decending' so you miss the 90% of folks who didn't list anything.
M's are around page 30.
