This was a flyer emailed to me in PDF format: Noxious Weed Eradication Day ("Let’s Pull Together") is a program calling for volunteers to donate time pulling noxious, invasive weed species from Central Oregon forests and open spaces. It’s taking place June 14th (Saturday) from 9am until noon, and volunteers will be provided with a BBQ feast at noon (if you’re in Bend).

Just bring a bag of weed.

This PDF is large-ish, at almost 2 megabytes, but contains the full details plus maps of where to go to pull weeds based on what neighborhood you live in.
