Sir, this makes my blood boil!
So, called the Johnson City, Tn City offices, and was given the phone number and extension of the VA Hospital Dept. of
Whomever takes care of The Cemetary;
(Ph # 423.926.1171 x 7814)
No One was available at that extension, and was told to try back in the morning.
So I called the number for The City Manager:
City Government
City of Johnson City
601 East Main Street
Johnson City, TN 37601
Phone: (423) 434-6002
Fax: (423) 434-6295
I asked to leave a message for The Mayor as to "Why the Crosses had been removed from the graves of Our Veterans?"
Said she would call back in the morning...
EDIT TO ADD:
Thank You Tugboat Sir...

"The Cemetery is actually co-located with the Mountain Home VA Center. This caused a bit of confusion because there is another National Cemetery located near Johnson City-the Andrew Johnson Memorial."
Heard from Them today reguarding WHY there were no crosses at Their Memorial cemetary: Was told that there are no crosses because, "There are no crosses allowed."
