It just might get into the 70s by tomorrow. So if you’re free in the afternoon, join the Nature Consortium‘s free monthly hike in the West Duwamish Greenbelt, 1 pm tomorrow (14th/Holly; map), RSVP to Lisa Corbin (lisa@naturec.org), who tells WSB, “There has been a lot of work done recently with the trails and an entire hillside has been cleared of blackberry and planted with natives, not to mention the spring growth of skunk cabbage, trillium, etc. A great time to see the greenbelt.” Then on Sunday at Alki, you can join the 5K to help fight lupus, a chronic auto-immune disease:

To be specific, Sunday’s event is the Seattle/Puget Sound Walk with Us to Cure Lupus Walk-a-thon (photo above is from last year’s event). The ALR Walk with Us to Cure Lupus event will be a 3 mile (5K) walk, starting at Alki Bathhouse at 9 am To be part of it, call Laurie Gray at 206.919.6270 or visit walk.lupusresearch.org/seattle (where you can also pledge to support walkers, if you can’t be there in person).
