Hams all over the world will be participating in "Field Day", an annual event that brings out everybody for several purposes- to test the ability set up 'in the field' during emergencies, being the most important one. However clubs also generally have special stations where YOU can "Get On The Air" (GOTA) yourself with the help of a control operator. You don't have to know anything about ham radio to enjoy a Field Day event. They might even feed you. ARRL.org is the website for America's premiere ham radio club, and you can find more there. You will certainly have some club in your area holding this event. Your local media may also have info. Go see some of what ham radio has to offer!
