Get yourself a bike barn. They're only about $400 and it's the only really manly way to cover your bike. Without it you stand the chance of being called a sissy or worse . . . a RUB.
Seriously - it doesn't make any difference at all. keep the baby blue blankey, It's a conversation piece.
I don't have the garage like most normal humans. Mine gets parked in a covered carport. When weather is bad, I have a gray/dark and light blue cover. Cowboys!!!
