I'm just starting to get involved with the "US. Original 13 Colonies Special Event Group", it's a ham event held around July 4 each year. The event focus is on a US military historical period. Only hams from the original 13 colonies can be Control Op Stations but any ham can make a contact and receive some cool documents. They also have a special recognition for Vets :-) See http://www.13colonies.info for more information.
