Anytime Jim,
I go out collecting quite often. I'm after a number of things, but can find a good amount in various rivers here. I'm about 2 hrs or so away in Gainesville. There's a native fish bunch that goes to the local swamps up there, road side ditches are excelllent, but are dry this time of year, you can find L. repens, mermaid weed, some lizard's tail this time of year. Closer to the coast, the better during this time of year.
If you want to collect down here, I can take you to several different places, Rainbow river is fun, Santa Fe is good also.
It'll be a canoe type trip. There are many pools to pick from along sides of roads, you can try there.
There's a group(NFS) up north in your region that collect fish and there's a few down in the Tampa region.
One of my cohorts is an Fish person here at UF.
Regards,
Tom Barr
