Atlantic coast bicycle route this summer?

[Westinghouse]

Here I am at 73 thinking about cycling the Atlantic coast this summer. Is it the quest for activity and adventure, or sheer madness? Maybe it is the sheer boredom of retirement and living alone in a condominium. One thing is sure. Temperatures are rising. Summer will be hotter than hell. There would be many places to eat, drink and get cooled in the AC. I would most likely start from southeast coastal Florida. Free (stealth) camping is the plan. I have done this coast route four times, and only once in its entirety from  Key West, Florida to Bangor Maine. Parts of highway 17 can be stressful, much traffic, narrow side lanes or none.  Who else cycled this route, and what were your experiences?

 Thank you.  I have not yet put the bicycle together.
