With the right helmet, riding is MORE enjoyable than going without one.
On hot sunny days the helmet and tinted visor keeps the sun off my head and out of my eyes. I can go with a hat and sunglasses but you'll always encounter just the right buffeting that'll wanna blow your hat off and knock your shades sideways.
On cool rainy days the helmet keeps me dry and the bullet rain drops off my face.
However, the ride to the beach, cruising, or getting groceries is a non-helmet affair.
