I hear you, Ed! I've never seen one in person. Waiting to stumble upon a box of them at a hamfest.

Shanon,

Dayton is coming soon. This will be the 40th year that I've gone. Amazing to think about that.

My brother-in-law and nephew live nearby, and my nephew is now 10-years-old so I think he's old enough to enjoy himself. If I go, I'll let you know, Ed.
