I con not remember a day in south Florida that i did not run my AC, and the coldest weather i have been in in the last 10 years was at the dragon, when it got down to 42 degrees. ( and the next day i left for sunny Florida. Rob was there and ask why i was leaving so soon, I told him I have a choice and my choice is to go south it may get cold as hell down here,, like 50 degrees,, but by 3pm it is time for the AC again. ,, now that is the life,, never having to be in cold weather.
