I was Webelos den leader, Cubmaster, Pack committee chair, Asst. Scoutmaster, & Scoutmaster before attending Wood Badge. I agree with the previous responders who said that a re-dedication to the principles of Scouting and bringing new energy back to my Troop were the most valuable things I got from that first course. Second was the toolbox . . . all of the teaching skills & ideas that I was exposed to for the first time or reinforced what I already knew.
Then, there's the Scouters. Over the 3 Wood Badges courses I've participated in, the people & the networking are amazing,
