I'm posting this on a couple of threads, and I know MOM would approve because she ALWAYS drinks her coffee and tea out of mugs, not paper cups: The Trust for Public Land will get up to $20,000 if you pledge to drink your brew in a mug. Of course they're hoping to sell java, but I unchecked the box about receiving further information.
