Each year the Four State QRP Group puts on a QRP convention called Ozarkcon in scenic Branson, MO. This year's event will be held April 7-8, 2017.
Ozarkcon is a great, relaxed time. It has a swap meet, a day of presentations, build-a-thon, etc. to keep the fun pumping. Branson has plenty to do for spouses or kids not interested in QRP and best of all since it's "off season", room rates, etc. are very reasonable.
