Folks, I understand everyones frustration. I wish I would have paid attention and followed the city / state drops as closely as those few people who did end up getting the best of the best. After I first saw this post though, I was able to register quite a few good city names, for example (Stroudsburg.us, SlipperyRock.us, Ayden.us, ParrisIsland.us, Millersville.us) among others. These are cities with populations of 5,000 people or more and definitely ones worth developing or reselling to real estate and travel companies. Out of the 6,000 city names with populations of 4k or more there are still probably a few hundred left available for registration, although they might not receive many searches or be the shortest, easy-to-pronounce locations.
And if you don't feel like taking the hours to dig through all the city names, compile lists, and search for whats still left then go ahead and bid on my thread "(3) .us Cities For Sale"

Best of luck, there are still a few good ones left. This will be a whole new market and I believe the extension of choice for finding anything city / state related in the U.S.
