Bob, I have some.
You gonna make the big show this year? As we have in the past few years Elisha and I will try to make an appearance at the Hamvention for at least one day. I'm not sure if it will be Friday or Saturday yet. Repeater-Builder will not be making an appearance at this year's show. It's just too hard to wrestle kids and such. With Kevin having a steady job again, it's tough for him to get off to go anywhere. (I don't think he's had a vacation since he got this new job!!) At any rate... Bob, If you're going to make the show, I can bring you what you need. If not, I can send it in the USPS. They still deliver mail don't they??
