Hi fellow Floridian! In my opinion, it's living in Fl, and the time of year, which is most responsible for snake sightings.
At our current residence we have seen 6 snakes this year, and dispatched 3 - one that was trying to get into my parked car, one slithering up the side of our house (weird), and one pencil thin corn snake that squeezed past defenses to get into the chick brooder and kill a chick it couldn't possibly swallow.
The 3 that kept their lives were all black racers that just minded their own business.
At our previous residence, in the same city, over 8 years we saw only 2 or 3 snakes. That was much more rural and bordering on a woodsy area with a natural pond. My theory is they had everything they needed out there so they didn't bother us. Here, it's more developed so maybe this patch of land is more appealing in comparison to the neighbors.
