Pete Seeger's dedication to cleaning up the Hudson River was legendary. His sloop Clearwater became a symbol of environmental responsibility and a hands-on source of education about the environment and the ecosystem of the Hudson River.
The name on the bridge will flow nicely with the river that flows below it. One in which Mr. Seeger did so much to help make better for all. It would be an honorable tribute, and likely raise (more or greater) awareness to people who may not already know of Pete Seeger's many contributions. (And hopefully inspire them to to find out.)
