Time: 4:30pm - 6:30pm

Organization: Arizona-Sonora Desert Museum
Description: This rare afternoon stinknet pull is to try to finish off a recently discovered patch that we worked on Saturday. Stinknet is drying out rapidly and will drop seeds soon. Mostly fairly small plants, with green left in some plants, while others are dry and crispy, and their seed heads are brittle. Snacks and swag provided!
Meeting Location: Same place as Saturday. North side of Wrightstown between Camino Seco and Pantano. Private residence. Make sure you go in the correct driveway. It will be during rush hour, and some people think Wrightstown is a freeway. Be careful turning into the driveway.
Event location: 8475 E Wrightstown Road, Tucson, AZ, 85715
Volunteers: 7 registered out of a total capacity of 15
Tools Provided: some digging tools, gloves, buckets, trash bags, some cardboard
Bring: favorite digging tool and gloves if you prefer to use them, 2 quarts of water
Wear: sun hat, long pants, close-toed shoes
Additional Information: Probably sitting or kneeling on the ground in a horse pasture with rocks, so long pants recommended. I'll bring some cardboard for kneeling and sitting on. Seed decontamination practices will be used to help keep us from spreading it further.
