I don't know what really happened, but I will say I've been seeing a dramatic number of inexperienced riders on the road, presumably due to higher fuel prices and with the warmer weather, they are breaking out old bikes or buying new bikes. Just today, waiting for my freakin tire change, not one, not two but three bikes came into the dealership crashed out and either on the hook or in the bed of a tow truck...
So, if you know any of these folks, take the time to talk to them, mentor them... Because their inexperience/death will be your reduced riding privileges / higher insurance rates in the future.
