Thank you for all of the information. I feel much better knowing that other dens have done this in the past and that it is perfectly fine.
I have loved every minute of being a den leader over the last year and this year. What he said (and how he said it) did not feel right to me, but I didn't know if there really was a BSA rule stating that meeting with another den made it a pack event. Because of this... I had a hard time defending my actions. I still don't really know how to prove to him that it is OK for two dens to meet. And, actually, I am resenting the fact that I am having to defend something like this. The negativity is very draining and defeating. It is certainly not what I signed up for.

For myself, and the other den leader, it didn't even occur to us at the time to include the tigers and webelos. Our dens have 2nd and 3rd graders..and it just made sense to get together because of what we were working on. This was 11 boys (2nd and 3rd graders)vs. potentially 21 boys (1st-5th graders)if we had invited the whole pack. To me that is a big difference.
