Vote for Sprinfield Armory
Apparently there’s going to be a follow-up to the state quarters program from the US Mint, and the state of Massachusetts has a page where you can vote for the historic location to use.
Under Hampden County is this little spot: Springfield Armory National Historic Site
Lot of great hardware came out of that place. Got Murdoc’s vote.
Big hat tip to the reader who sent this in.

“Springfield Armory National Historic Site”
That won’t ever make it, not politically correct
[...] Apparently there will be a new issue of the state quarters done by the US Mint. Massachusetts is letting people vote on a National Historical Site to appear on the back of their quarter. Gunpundit has a really good suggestion. [...]
I would have thought Lexington and/or Concord would be a good choice. Then use a tag line of “Site of the first attempt at gun control in the U.S.” or similar words to that effect.
I agree with Huffman, both the location and the sentiment.
