Natural history workshops in Maine

Want to learn about nature while lodging at a field station in Maine, USA?  The Eagle Hill Institute has opened its registration for this year's courses and workshops.  Most courses last several days and focus on a specific topic (e.g., crustose lichens, salt marshes, ferns, etc.).  Different courses are targeted to different levels of expertise, and the fees seem reasonable.  The Canadian Field-Naturalist is not affiliated with the institute, but our readers enjoy natural history so I thought some of you might consider these courses the perfect vacation this summer.
