As a geographer I always need to drive to the end of the road, visit the northernmost, southernmost, highest, lowest, whatever. So Key West and the Florida Keys were of course high on my list. I had problems again with a lack of time and scarcity of options to stay overnight. Next time I will plan better and maybe stay overnight on Key West itself.
Perhaps the best day of my 2015 expedition was the boat trip out to Dry Tortugas National Park. I had considered camping there for a few nights, but decided against it because of the extra gear I would need to carry along for thousands of miles. But next time I will do it!
