I've found some, less than 10 all told. I'd probably ask Bow Only, he finds a lot more points than I do. These were in an old borrow pit for a train track right in the middle of town.
These were all found in a borrow pit that is about 100 years old next to a train trestle that is still operable (the sign on the bridge says 1919, so that's how I know). The soil has eroded off of most of the pit, so it's mainly exposed red clay. This was my 2nd foray into the pit; the first time I found a few pieces of flint and just loosened a lot of the clay on the banks with a shovel. After the rain I found these exposed, along with some broken tips and bases. First Dovetail I've found in Florida in 20 years, so I was pretty pumped.
