Welcome to the forum Bob.
Despite living in Northern Ireland you have another person with the same interest. Have visited in my younger days Gettysburg , Cold Harbour and a few other Battlefields. Very impressed with Gettysburg was able to tour. Also visited a gun shop and museum. They went out off there way to show me some of the original weapons after they found out that I had an interest in the period. The same person told me he played Nathan Bedford Forrest in the film Gettysburg along with Martin Sheen.....
