As George Thouroghly-Good says "Everybody funny now!".
I find it funny that SCCA totally disregarded their own policies, guidelines, and rules for 4 decades, as they kept threatening to reduce classes while they kept adding classes ...... then, they have gotten out the label makers, and suddenly feel the need to relabel classes, which will still be running together on track in the same race groups. I am not sure which analogy is more appropriate .... "letting the horse out of the barn" ..... "herding cats" ......"rearranging the deck chairs on the Titanic", but elements of each apply. After 4 decades of doing nothing, there really is little that can be done now, other than symbolic gestures, that only serve the purpose of disenfranchising racers. Perhaps sad is a better adjective than funny.
