After the trip - a few drifts in the same area!

Not happy with the last two trip outcomes, I did a few drifts after dropping my clients off was rewarded with two keepers 19 and 21 inches. It just amazes me how you can have perfect conditions (tide, wind, etc) and they don't bite, yet after the trip I ended up fishing the wrong tide and keepers start biting!! Tough to figure out.
