I used to work at Seven Ranges Scout Reservation in Ohio from 2001-2003 in the "ecology" department and we taught a ton of awesome merit badges like Bird Study, Energy, Atomic Energy, Space Exploration, Environmental Science, Fish and Wildlife Management, Forestry, Geology, Mammal Study, Nature, Oceanography (yes, in Ohio lol), Reptile and Amphibian Study, Soil and Water Conservation, Weather, and Astronomy (my favorite). Fun times!
Thanks!
