Did contractors (and retirees) have to take the course to get stickers for their motorcycles previously? If so, I'm willing to bet that you'll be taking the course...
Right, but the message, and the instruction its drawn from specifically say the retirees are exempt from the refresher, and darn sure I'll have a copy of that in my pocket when I renew my sticker
Like anything military, you go by the book, and he who has the book on his side wins
You still need it for that initial sticker, just not for renewals.
