When is the last time you were on 30-A? Do you know what area changed speed limit? And If there was a fatality or even a car versus bike, it was the biggest cover up in recent history. I agree with you about 25MPH from west toe of Western Lake bridge through old Seagrove-east of there to HWY98 I have no problems with the current limits, save for the 25MPH in Alys, but it isn't too annoying.
I have accepted golf carts as a reality that will never go away in Seagrove, Seaside, etc on 30-A-I don't like it, but I can accept it. But I can't see why we need to sell out to tourists who might want to piddle golf carts on rural 30-A. The area you identify as rural is almost wholly similar to a big chunk between Grayton and WaterColor recently transformed into 25MPH!
I'm on 30A everyday, and yes i know exactly where the change took place. also the car versus bike was not on 30A, i'll see if i can find the article, but it was in south walton.
