I have been a member of a local Freecycle group for several years and I've had a chance to give away many things that normally would have either been trashed or dumped at Goodwill. For those of you who are not familiar with Freecycle, here is a blurb from their website:
"The Freecycle Network™ is made up of 4,552 groups with 5,485,000 members across the globe. It's a grassroots and entirely nonprofit movement of people who are giving (& getting) stuff for free in their own towns. It's all about reuse and keeping good stuff out of landfills. Each local group is moderated by a local volunteer (them's good people). Membership is free."
