Fishing with night crawlers and worms is always productive, but for some of us, especially children, getting that night crawler on the fishing hook can be slippery business.
When fishing with night crawlers, try keeping an old can half full of sand by your side. Put the night crawlers in the sand and drag them around, then put them on the fishing hook. The sand makes it very easy to grip, especially for the youngsters, and it is fun for them. As soon as the night crawler hits the water, the sand is removed. Good luck and good fishing!
