I fished with my dad as a kid mostly stripper fishing some bass and a little crappie. I don't remember what we did or where we fished. We always caught fish but I don't remember how. For the past 15 years I have been fishing offshore and forgot how to freshwater fish. A few years ago a friend took me trolling for crappie and I fell in love with it. Now I have 2 boys a boat and some fishing stuff. I've been watching a lot of videos and stuff on YouTube. My questions are
1 on sunny days use a darker color jig or lighter?
2 in murky water brighter?
3 how to locate crappie? I know they like brush but I here about drops and ledges how deep?

I went a few times last year and caught a few fish but was only successful 3 times out of about 10 trips. I plan on fishing hartwell, greenwood, and succession.
