I'm not sure what that is...
What I'm thinking is kinda of a round robin with your mascot/journal. If I get 5-6 Dens, each den has a mascot/journal and a list of participants and a calendar of when and where to mailout your mascot/journal. You should get 5-6 different mascot/journal during the year to share with your Den. Journal, add pictures from your Den then send it on.
