Nice work, Patrick.
I just spoke with someone at the state department of fish and wildlife (about something else) and asked him about the band number. He said that usually there would be five numbers after the dash on the band. There are usually three or four numbers then a dash and then five numbers. Any chance you can find two more?
However, he did say that it is unusual that Buzz was banded on his left leg since most banding is done on the right leg. This fact may help identify who did the banding.
We're getting closer!
