Thanks for the comments and suggestions.
after some thinking of my own as well as reading here and considering all of the opinions, I think the way I will handle it is this: I'll speak to the cubmaster and see what he thinks.
While i would love every opportunity to wear the scout uniform with pride, I don't want to take a chance of confusing anyone or to be seen as disruptive or intimidating. I'll ask the cubmaster how he feels about it and what he thinks, and abide by his decision.
Personally, I wouldn't wear the uniform to den meetings at all. Regular pack meetings are iffy, but I'm kind of leaning toward not wearing the uniform then. After all, I'm there as a parent, not a leader. For a B&G - that, I would be tempted to wear because that's a big scouting event. In our pack, that's when all of the boys receive their rank badges, so it's a big celebration of scouting. for any other major scout event (Scout Sunday, Cub-o-ree, Day Camp), I would definitely wear it then.
But for events involving the pack, I'll defer to the preference of the Cubmaster.
Thanks!
