We like nothing better than to ambush people with old time music in the great outdoors. The setting on Saturday was a work party, partnering the University Childhood Development School and the Nature Consortium in the iconic battle of humankind versus invasive plant species. The good families of UCDS put on their boots and gloves and planted trees at Pigeon Point park, part of the Duwamish Greenbelt.
The history of old time music frequently includes accompanying, or following, community work events -- or "workings" as they were sometimes called. I suspect the adults and children planting and mulching trees were working harder than we were, but we all sure had a good time.
If you want to explore volunteering with the Nature Consortium folks, they are always eager and ready to accept your efforts. Check out their projects at their website: http://www.naturec.org.
