Yesterday, I did go to the American Military Cemetery of Henri-Chapelle and picked up the two certificates regarding the adoption of the graves of Sgt. Homan Jackson (4AD) and Pfc. Leslie Banaka.
I also heard there that there will be a new Superintendent and he/she will no longer issue these certificates. That's not really good news. 
I also visited the American Military Cemetery of Neuville-en-Condroz also known as the Ardennes US Military Cemetery. Here, I visited the graves of the 6 Americans - 5 Glidermen and the Glider Pilot - who were KIA on September 17, 1944 in my area (see my topic "Glider Monument".
There, I saw a WWII Veteran visiting the grave of his buddy.
Even after 63 years tears were still running.
I respectfully kept my distance and only said a friendly "hello".
If someone's interested, I might open a separate topic with some photos of my little trip.
Erwin.
