I don't think any are too obscure, necessarily (though I hadn't heard of many), but I did think of Independence, Kansas, and Salina, Oklahoma, first. I got both eventually, and the ones I thought of are much, much smaller - I just live closer to the two of 'em. Great quiz!
i missed the four weakest answers that most every missed so I guess you could reconsider those four states. for sure not being in alpha order makes it more difficult as it is hard to see at end what you have left off. great quiz!
