I'd love to add places you know of where people can go to study nature...please let me know what's in YOUR area, and I'll add it.
Close to where I live is the Martha Lafite Thompson Nature Center, where I've spent many happy days sketching and studying. If you're in the Kansas City/Liberty area, check it out!
Lakeside Nature Center in Kansas City's Swope Park is lovely, with a stunning new interpretive building...and of course the Kansas City Zoo is there, too, with plenty of opportunities to sketch.
Powell Gardens, near Lee's Summit, Missouri, is a gorgeous place, a botanical garden with a variety of habitats.
Burr Oak Woods Nature Center is one of the Missouri Department of Conservation sites you won't want to miss...an interpretive center, nature walks, library, auditorium and more...
Farther away is the North Cascades Base Camp, with art workshops...check it out!
