Congrats and good luck! I had my first troop a couple of weeks ago with one other member of the Ohio Garrison and like Steve said, you will remember it forever. I can't stop looking at the pics a buddy of mine took for me. I did end up having a kid who followed me non stop....he started out okay but just kept at it. Even to the pointy of my buddy taking a couple of stickers off my back. I learned payin attention to everyone at the event was the best thing to do. I greatly appreciated havin someone there with experience but I also learned it's best to walk around, carefully! As if looked and walked around, I waved and held up my hand to give a high five to gauge the kids reactions, even the adults as well. Some parents of the kids that were hesitant walked over to me and gave me a high five to show their kids it was okay....of probably close to 50 to 75 kids, only one cried....I felt horrible but the father gave me a high five. One time while walking around, I looked over to see a girl in a wheel chair and she had a huge smile and just waving at me....it was a wonderful feeling. A couple of other kids told me about their toys, a little girl kept telling me she wasn't scared of me cause she knew my blaster was fake.
Steve and Brian obviously gave the best advice....while we love what we're doing, seeing the kids and adults smiling, wanting pictures, the best thing for me to think about is we're helping them to forget whatever their problems are, even for a little bit!
Good luck!
