Today is Field Day, an emergency preparedness exercise for amateur radio operators! The goal: set up a temporary station, and then make as many contacts as possible over 24 hours.

Check the Field Day Locator to find a station near you. Many stations are set up like an "open house" and welcome visitors.
If you make contact with K2HAX, let them know that Rey said hello :)
