Roy,
I even stopped going to gun shows with my buddies. The last time I went I was only halfway around when the rest of them were ready to go. This was even with my rolling walker. Before I retired, I lived in Columbus and set up at every gunshow. I mostly visited with old friends and watched for deals. I never sold enough to cover costs, but since I didn't have Motel bills and only ate one meal/day away from home it was worth the cost to have somewhere to sit both days. I mostly setup next to a good friend and when he walked around, I watched the tables and when I was gone, he watched. I always had a good time and found good deals. Sadly, Agent Orange got my Columbus buddy and this year one of my main local friends. I have good memories though. If you have a table, pretty often people sell their dad's reloading tools and components. I've often gotten good deals on powder and bullets and even some equipment sometimes. Twenty-year-old prices are usually pretty good.
Now I'm mostly trying to finish up projects and gather enough tools for my grandsons and great grandsons to have shops. If they lived closer, I could teach them, but they don't. Now, I will have to give them directions how to make cased and bullets for the guns I will leave them. This includes the conversion factors from Black powder to 4198 from Cordite to 4895 and from R5 to VV140 or 4895 and how/why to anneal the cases they make for those guns. This is obviously second nature to you, but someone will have to teach them.
Years from now, if someone needs help; I ask that you help them, you never know whose grandson or great grandson he will be.
Mike
