The Danbury Volunteer Fire Companies will arrive in a caravan of fire trucks at  Family & Children's Aid tomorrow morning.  They will be led by Santa and Sparky The Fire Dog, loaded with gifts for the children.  Starting on Black Friday, the firefighters collected donations outside of Toys"R"Us every Friday night, sometimes in the rain and snow.  They will unload toys from the fire trucks in Bucket Brigade Style, filling the non-profit's gymnasium with toys.  This is the fourth toy collection for Family & Children's Aid.
