Top and doors say off for the summer. Doors and windows at home, but with the top folded down.
So far this summer I've been caught twice in what I'd consider dangerous rain. Even with the top on (no windows or doors), the rain was blinding - so much so that not only was the inside of the window soaked, but it couldn't keep it out of my eyes to see. I don't mind cruising around in a light shower, but in a heavy thunderstorm is stinks.
Having said that, there's a 40% chance of thunder storms today so I brought my raincoat... 8)
I should probably get some goggles too.
