If any local Jeepers are interested in ham radio this weekend is an emergency preparedness event called Field Day. Clubs/Operators set up stations run off battery/generators and try to make as many contacts as possible in a 24hr period. Some clubs offer test to get your ham license and most stations have a "Get on the Air" station so non hams can take a swing at it.
