DNJ,
Yes I too remember it well and the spitting on us as we walked through the terminals on coming home.
I still see homeless vets under those Interstate Overpasses.
I served in Korea and stayed in through Vietnam and I don't regret a bit of it and would do it all again for our country.
I was in the US Army Reserves during that time and fortunately did not see any action, but I could not believe the treatment the Nam vets got...
