I agree weith permafrost! When I was in Florida last week Id get up to the airfield and in the air by 0730. That way you can enjoy the calm, clear conditions, do 5 hours and you are back on the ground for lunch! Some days if the weather looked good enough Id get more in - up to 8hours!! But being 6'4" in a 152 for that long wasnt that much fun!!!
True....Florida and the east coast start getting very bumpy and scattered TS are almost a daily occurence between now and the end of the summer...plus the hurricaine season starts june 1st!!
As I mentioned in my earlier post...if its Florida you decide then Sunrise Aviation works out at approx $60 and hour for their 152's (Just done a currency conversion and thats 31quid an hour)!!!!! Their aircraft are very well maintained and you'd get it block booked for at least 5 hours a day if not the whole day!!!
I didnt look further north so cant advise but if its Florida, although very busy, does give you good practice at a busy environment. Id highly recommend visiting not only the remote, uncontrolled airfields but also the likes if Savanah International, Orlando International, Daytona Beach Int. Its awesome fun being slotted in between big jets in a 152!!!!
