Thanks all.   I happened to run across the link provided by auntietk while searching the web for information. 

I came to the same conclusions that in this case there should be no legal problems.  I am also confident no one should think I was sneaking photos of kids for perverted reasons.  I'm still not sure if I will ever post any of the photos though.  I want to but I don't want to at the same time.  Some of the expressions of delight and pure joy are evident on the children's faces.Their safety is foremost above any personal satisfaction I would get in posting the candid pics.

I think I just talked myself out of posting.  Whew!

Maybe next year...
