Every year, there is a ham radio festival in Xenia, near Dayton, Ohio, with thousands of booths, displays, and vendors, all dealing with various aspects of Amateur Radio. I took many photos but this was the most interesting. Hams are both national and international. They support their country, their local and national governments, and spread goodwill to all nations. Sometimes, a ham radio operator will talk to someone on the other side of the world, and he can do it with only 100 watts of power. To learn more, go to ARRL.org.
