Well, maybe not as good as a t-shirt, but it's not bad.
Last year for ALS Advocacy Day I had some nice buttons made up for PALS who had self-enrolled in the CDCs National ALS Registry or who were in clinical trials (or both!). The idea was for them to let their peers and others know of the good deeds they had done. This encourages others to participate and starts some good conversations. It was nice to see so many wearing them when we went to Capitol Hill. They are large and readable buttons.
