I also spent 20 months in Vietnam and spent it in the back of a C130. I remember those 55 gallon drums with Thor orange band. There were times when I and other team members slipped in the wet agent orange from drums leaking. Today I have bad tremors and it may take many months to see a neurologist. We were just young men doing our duty for our Country. My prayers are with your husband, and stay strong and god bless you.
