In my other life l used to leave my helmet on my bike without a second thought. Now, no. I saw two Harley’s parked in the lot of a mall a couple days ago and the riders had left their helmets sitting on the ground next to the bike. I thought that was nuts but maybe they believe in positive karma. Do you carry yours with you? Lock it on your bike? In this day, there is just no way I am going to leave such a personal and expensive piece of gear like my helmet laid out for an easy grab by some douchebag.
