The Pussy Hat project was so successful that a number of scientists who are knitters (or knitters who happen to be scientists?) have designed hats, headbands, and armbands with symbols that reflect their field.  You can find them here.  Here’s a link for information about the March for Science on April 22nd.  However, other marches are being held more locally in Lancaster and Concord.

As the snow melts, trash begins appearing on our roadsides, and I remember the Keep America Beautiful campaign which was so vocal in my childhood to counter the litter problem.  Every Earth Day, local groups–church youth groups, Girl Scouts, Boy Scouts–would walk the roads picking up trash.  So while walking, or marching, don’t forget a receptacle to pick up the trash you pass.
