[George Gafford Sr]

Hi Tom, Thanks for wanting to help me out on this.
Saturday is good for me. If OK I'll stop by after noon in hopes to get this right.

Hi George,

I am available pretty much anytime this weekend. I have a few things to do on Saturday morning before noon, but other than that my time is open. Let me know what is the best time for you and I'll put it in my schedule.

73,
Tom
