My son lives in Princess Island SC. I had a Jeep Wrangler with both soft and hard top. I went to visit him at work in Paris Island and had the top off and actually had to put on the AC once I got to the base. Same here in Massachusetts, I took the top off the night before I went to work, put on the heat and by 430 I had to actually put on the AC when the top was still off....never again will I but a convertible, just my 2 cents
