I'm going to have my kids work on the cub scout requirements for the international spirit award, but I got really lucky in that I grew up in Belgium. We're going to visit my family there this summer, and I contacted the local scouts unit to see if they could visit while we're there. There's a slight chance they might catch their last meeting before the summer, but if not the scoutmaster will set something up just because they're visiting.
On a related side note, is there anything they should take to exchange with them, like council patch or something like that?
