At 9 am this Saturday meet by the SF Bay Crest trailhead at the Old Tunnel Road staging area.
On the Orinda side of Sibley Park, the weather will probably warm up fast, so be sure to bring a hat and water along with a pair of gloves.
We have loaner gloves but cannot ensure a good fit.
Stinkwort, a.k.a. Dittrichia graveolens, will be bolting and sending out new flower buds.
For that reason, you're welcome to bring a pair of shears or clippers if you want to search out and cut down stinkwort; it's an annual so it will not regrow if you cut it to the ground.
