The Rails to Trails Conservancy (http://www.railstotrails.org/index.html) helps convert railroad beds to recreational trails, and cyclists are a big beneficiary. Simply by casting a vote at this website (http://www.takepart.com/membersproject/vote) under Arts & Culture, you can help Rails to Trails get a $200,000 grant from American Express. You can vote as often as once a week through May 24 and support them with just a few clicks (instead of a few dollars, which I'm sure they would appreciate as well ;)). Top 5 vote-getters get the cash and currently Rails to Trails is #3.
