I took a trip out to the museum today - something that I had been planing to do for years. I'll add the names/designations if/when I get the chance. Most of these shots were taken with a borrowed 10-22 lens, which really worked well for the trip (thanks John). A few (the later ones) were taken with the 70-200 lens.
It looks as though you had a nice day for your trip. They appear to have quite a collection of armament, both old and new, and even some foreign equipment. I must admit that although I have lived in Maryland on and of for twenty some odd years I never got up to Aberdeen. Now, your photos make me want to go.
