Anyway, there are only two ways it could have gotten there: a) it fell off of somebody else's vehicle and a passerby put it on my car thinking it was mine, or b) someone took it off of their car and put it on mine on purpose (kind of like a "random act of patriotism"). The latter is definitely my favorite, so that's what I'm going with.
Hopefully the driver will enjoy spreading the message of patriotism for a few weeks before they "pay it forward" and move it along. Or it will end up in the trash. Either way, God Bless America!
Humorous note: Both Angela and I independently came up with the phrase "Random Acts of Patriotism". Talk about a perfect match!
