•Here are the opening hours for the next several days at our two interactive, educational, shop-and-think, nature-and-science spaces, in Northeast Harbor (115 Main St.) and Seal Harbor (16 Main St.):

Sept. 21 (Thurs.) Seal Harbor open 11 to 4, Northeast Harbor closed; Sept. 22 (Fri.) Seal Harbor open 11 to 4, Northeast Harbor closed; Sept. 23 (Sat.) Seal Harbor open 11 to 4, Northeast Harbor closed; Sept. 24 (Sun.) Northeast Harbor open 11 to 4, Seal Harbor closed

• What will you find at those two spaces? The Seal Harbor Naturalist's Notebook (three floors to explore!) has been named a Best of New England destination by Yankee magazine and a Best of Maine destination by Down East magazine. We don't call either space a "store" even though there's a lot of wonderful, intelligent and playful shopping to be done in both spaces. They're more like an experience—a fun exploration of the natural world, science and the history of the universe. You are a participant in a walk-in, 13.8-billion-year nature-science art installation. As one visitor to the smaller, Northeast Harbor Naturalist's Notebook said this week, "This isn't a store, it's an education!" 

•Send us your nature photos and sightings by posting them on the visitor-post section of our Facebook page or by attaching them to either a Facebook message to The Naturalist's Notebook or an email (info@thenaturalistsnotebook.com). We'll post the best of them here or on our Facebook page, which has become a hub for nature and science lovers from across the country and around the world.
