Coldest you have driven your convertible with the top down?

Maybe in the 60s. I remember January 1984 we had three cars (but the '66 Barracuda was in storage), a 1980 Omni 2dr and the GTS. Our son's crib wasn't going to fit the Hatchback (or it was full of my tools and parts for work) so we took the GTS to K-Mart. It wouldn't fit in the trunk or the back seat with the top up. So, the top went down. It was unseasonably warm that day, though. I think it was in the 70s..
