I can’t recall the author’s name, but I remember seeing a few years ago a man who wrote about a book about life in a motorcycle gang and his readings/signing were at local Harley-Davidson dealerships, not the local Barnes and Noble/Borders. It stuck with me because I was writing a teaching methods textbook and I thought, “why not educational supply stores for mine?” But you’re right, this is a good place for a little creative marketing!
