The most well known PD pin in Washington is currently available from PAN. It has the letters PD in black on a white background with a red circle and slash going through it. You can get the pins by sending your snail address to Mike Claeys [log in to unmask] (Parkinson's Action Network) If you need a lot of them for your group or to further distribute to your congressmen, PAN will gratefully accept a donation to help cover the costs.
