Note that there are one or more hamfests listed on the club calendar in Virginia or neighbouring states almost every weekend for the next 3 months, except for field day and independence day. Of particular note are Manassas (2014-06-08) and Berryville (2014-08-03). The Roanoke hamfest is also the day before Berryville, and the sponsoring group has reached out to our group to encourage attendance (they schedule it when they do for the convenience of vendors, though it is inconvenient for attendees). Also, the Virginia Beach Hamfest is 2014-09-14 and the Mid-Atlantic States VHF conference (PackratVHF) is a 3 day event in PA starting 2014-09-26.
