I'm just starting to fish Crappie.I sold my pontoon and purchase a Jon boat and a ok fish finder. Last week I put out two brush piles in two different coves. I'm fishing Lake Hartwell in the North West corner of South Carolina. I put both piles in 22 foot of water, they are each about 12 foot tall. Used sand bags for anchor and 1 gallon milk jugs to keep them vertical. I'm after feed-back and don't mind criticism.
1. How would you fish them?
2. How long does it take Crappie to find and congregate around brush?
3. Any good ideas about improving them or better ways to build the next set of brush piles?

I have 7 grandkids I went to impress with my new found skills and cunning.

Thanks much for your reply,
John
