Hi Donnie,
Welcome to Crappie.com, lots of good folks here willing to share their information in a friendly way.
I am learning as I go, just moved to Florida a year ago this month.
If you have lived in POLK County you have probably heard of many of these places. I would check out the Bait and Tackle shop at Saddle Creek, also the Big Fish Tackle store in N. Lakeland for starters. They will help, in which lakes fishermen are catching different species. Tenoroc is a State managed fishery, if you Google, will give you all info needed. If you buy the Ledger on Thursday, they give a pretty up to date fishing report, for many of the area Lakes. Another place is the Winter Haven Chain of Lakes.
If you are targeting Largemouth Bass, I think they are in every Lake and small pond around!
I have leaned more towards Crappie, and I am starting to find them more and more, as I discover the many different Lakes in our area.
Good luck, I hope you and your girlfriend, enjoy fishing the area as much as I do.
