Hitting some old spots

The last 2 weekends I hit some old spots I havent fished for awhile week before last only 5 crappie in a few hrs at that spot this week got 17 nice yellows 4 pickeral and 1 big ole bluegill , hadnt fished that spot for almost 20 yrs .Wanted to do some recon and I did but I forgot my depthfinder made it tough to scout the area real good but had fun .Used weight and line to figure I caught em in 8 to 10 ft .Gave my go to crappie spots a break . Having trouble with phone pics for some reason .Cold temps coming this week hope we dont get hard water .
