Wife and I were out riding last night on a local highway. Shortly after hopping on the road, a cager went by and pointed to the rear of the bike. Right after that another guy did the same and opened his window shouting "you lost a bag!" Sure enough, I hadn't secured the right bag (Boss Bag removable) correctly and it bounced off. We were able to go back and recover it...only minimal damage to the bag. Thanks to the cagers, we have our full complement of luggage! And, I've learned a lesson on checking the security of the mounts!
