Watching some of the Daytona coverage on Speed, only 15 degrees cooler here than Daytona beech (30 here, 45 there). I'm sure if the sun comes out there will be people out wearing shorts. Lowest temp that we've ever done top-down cruising is 49 degrees. That was a convertible club run and our first stop was 20 miles down the road. Some how the heater just doesn't seem to work well at those temps.
