I have only been out five or six times this year on the local lake. My son-in-law and I finally got his used Express fishing boat fixed up and running with a motor rebuild, a Garmin Striker Plus fish finder, a Motor Guide Xi3 trolling motor, and the live wells re-wired and working. But the summer hasn't been kind for catching fish. Between the excessive boaters and vacationers, and the intense Texas heat, we haven't caught much. So we pass the time with a lot of practicing using the fish finder including starting to contour map the lake, way pointing groups of stacked fish, and learning the layout of the bottom. Also spend a lot of time practicing casting techniques, such as flipping, skipping, and unfortunately clearing snags. Some time is also spent teaching my son-in-law knots, rigs, and baits to use and how to fish them. Hopefully this will pay off in the fall when temps fall to a reasonable level and all the vacationers and excessive boaters go home for the winter. How do you pass the time when the fish aren't biting?
