Welcome. I have a Lions Den, officially of three, but now, practically , of only two. It seems like a lot of games I see for Den activities cease to be practical when you drop from three to two Scouts. But I'm hoping these will be nucleus of a stronger, bigger Den next year when they hit first grade.
You're in good company here. Many fellow Scouters, like myself, who returned wondering (hense my "WonderBoy" screen name) how to put on a good program. But more importantly, many, many Scouters with plenty of good experiences (and some bad ones to learn from!) to share.
