I’m the Director of Information Technology for Rails-to-Trails Conservancy and we’re conducting a GPS mapping project that could really use your help. We’re mapping all the country’s rail-trails for the first time ever. This data will be freely available to the public on our website TrailLink.com. The help we need from you is easy – all you need is your GPS receiver. We collecting GPS tracklog and specific waypoints for each rail-trail. Please visit http://www.traillink.com/gps.aspx for more detailed information or feel free to email me directly at email@example.com.
Thank you for your help!
