I live in St. Augustine, FL a bit south of Jacksonville,
The pool I have been swimming since the reopen is closing up this weekend for the season, it is a small 5 lane 25yrd pretty close to my house. The city has a larger heated 25meter pool that I normally go to when my pool closes. However this is the same pool that now three high schools are using for practices so only 4 lanes in this pool are open at most times and no lane sharing. I believe during the other slots of time one can just get 45minutes of swimming before they give you the boot. It is a bit odd that in FL you can basically have a free for all at bars and downtown but pools have more restrictive rules

If anyone knows of some spots in Northeast Florida let me know below.
