Most of us that reload like guns and girls. So that is what most walls will have. I have four Ammo-Plants so you can't see my walls so I don't have anything on my walls. But I have helped many get their Hornady up and running. I have noted what is on the walls but none stuck in my mind except one. On another forum I had a guy ask me for help in getting his running right. His English was a little better than my Spanish, and even after we talked on the phone it didn't help. I let him know that I would be driving by his place in about 4 months and let him know that I would stop by and help him out. After about a half-hour I go his Ammo-Plant running like a clock. That is when I looked at his wall.
Now, most of us take for granted what he had on his wall. There were 2 American flags on each side of a document in a frame. That document was the certificate of his US Citizenship.
Two years later I stopped by a visited him one more time and he added one more certificate. He is a proud member of the state of Utah's State Sheriffs office.
That is the BEST damn wall I have ever seen.
