Cities Puzzler
This is my infamous cities puzzler.
The following US places have a common property that no other US place can claim. Can you figure out what that property is? The answer is simple; it does not require special knowledge or bizarre facts. I can imagine the possibility that I have mistakenly omitted as many as two places, though I very much doubt it. Such an omission on my part will not, in any way, hinder finding the solution. Don't bother guessing, you will know when you find the solution.
One person has independently solved this puzzle since I formulated it in 1995. That solution came in 2010.
September 5, 2007 Note: This list is notably different from past lists. The two reasons for the differences are (1) I have mistakenly left off Laramie from recent lists even though it was on past lists and (2) properties change, note some additions and deletions relative to the previous list.
