While looking up information, I found that there is the Air Combat Museum just across from the terminal building. It seems to be highly rated; if it’s open it sounds like a good way to spend an hour or two before your flight!
The web site notes that there’s a USPS drop box outside of Door “B”.
Robert updated in 2021 that there is now a blue mailbox across the street from Door “C”. It’s not that much of a change from the door “B” location (perhaps a minute extra to deposit a letter).
Collection time is Monday-Friday at 10am.
