your good till the end of march here in hoosierville.
Brookville wont freeze back over. heck its been a few years since it froze up like it did this year. However where i was fishin, there still was some remaining ice in the standing timber(can you guess where i was fishing? LOL) that might tighten back up, enough to cause boating probelm. But the main lake should still be wide open, even with a week of temps like this.
I too went back a few days ago, and found the same crappies as before, except they refused to bite, or even follow a bait.
