Interesting stuff!

I was licensed in 1967 so I'm just a youngster to you all. But I started
subscribing to both QST and 73 shortly after I got my Novice license.

I met Wayne a few years ago at a local hamfest, where he was a guest
speaker. I have to say he looks really good for his age!

73, Zack W9SZ
