Good luck over in the sand. I retired in 89 then got recalled for Desert Storm. Then came back to find wife had been reassigned to the Pentagon, while I was gone. So I got to spend a lot of time in the district. While you are there I know you will see the Smithsonion, but also see the NRA museum just outside the beltway. Also Andrews AFB, where Air Force One flies out of, Has a good skeet range. That was the only way I maintained my sanity, I shot skeet every weekend.
