Mark,
As some of the area WIXers may know my family often attends airshows and such with me. We almost always take some copies of a film called The League of Grateful Sons (I know the folks who produced it pretty well) and hand them out to veterans. We used to always hand them out to WWII veterans, but of late have been giving them to Vietnam and other vets as well. Often we'll spot someone before they realize it (funny how some guys you can just tell...) and will ask them if they served in the military. The next set of questions follow such as where did you serve, what did you do, etc... Most are willing to talk, but even if they're not or say that they don't want to talk about it we'll thank them for their service to our country, shake their hand, and offer them the DVD for free. Of course sometimes we try a bit harder than others to get a story out of them with a question like what was your most memorable mission. I've heard some good stories out of that question.
You would be shocked at the number of Vietnam guys we've talked to who've cried and mentioned that no one has ever thanked them before. Now my family doesn't particularly "like" the Vietnam War as I would tend to believe that it wasn't necessarily a "just war" but we still recognize that most of these guys honestly believe that they were doing what was best for our country, had honorable motives, and the forces that they were fighting against were really and truly bad guys.
I personally think that the keys to having good conversations and establishing a relationship with a veteran are really the foundations of any good friendship. Honesty, sincerity, kindness, patience, respect, etc... It helps if you ask good questions, don't make yourself look too stupid (It's ok and sometimes helpful to ask a few stupid questions if needed to make them feel like an "expert"

), and PAY attention and listen. You might pick up on a subtle thing that leads to a much more interesting conversation.
Oh, and dressing respectably and using good manners (look them in the eye, don't drop slang, etc...) doesn't hurt either with the older generation especially.
