2020 Pull Together

Thank you for attending the 11th annual

Pull Together!


The 4-County Cooperative Weed Management Area (CWMA) hosted yet another fantastic event at McMenamins Kennedy School! With over 150 people in attendance, the CWMA is excited to have had their highest attendance yet! The group braced the dreaded snowpocalypse and enjoyed plenty of coffee, snacks, and cozy couches. Thank you to our fabulous speakers and attendees for making this such a fun, memorable event!

The talented Jon Wagner of East Multnomah SWCD illustrated the event through some rather entertaining comics. Check them out below!


If you missed the event or would like another recap, our speakers are generous enough to share their presentations with you all!
