Brandenton Motorsport Park in Bradenton Fl (1.5 hour drive from Ft. Myers to the North). Its up kind of close to Tampa. There's also Emmokelle Dragway 1/8 mile down in Emmokelle.
But BMP is the place to go (well prepped 1/4 mile track). But its really hot and humid down here. I would guess the DA is 2000+ during the day.
Here's the website for Bradenton Motorsports Park.

They are having test and tune from 10am - 2pm on Saturday.
Good luck if you go, but it will be hot.
