This was a really good sized hamfest years ago when it was at
Stricker's Grove, I used to get there at 5 AM just to get set up, then stay
all day in the sun. Now years later it has really been downsized to the small
fest it is today. Still it's a good chance to find some bargins on those
radio knick-knacks you need!
I'll see if can make it out there this year.
