From New Madrid, Mo.: Students at an elementary school are collecting postcards from all 50 states to commemorate America's 250th anniversary. The project began with a Facebook post and has gained momentum as people send in mail. So far, postcards have been received from a variety of states, including Texas, Oregon, and California, as well as South Dakota, Arkansas, and Mississippi.

The school has also received postcards from Tennessee, Alabama, Georgia, and several other states. Some states, like Georgia, responded quickly, sending in multiple postcards.

Further details about the project are available from the source.
