Gathering natural fish bait is part of the game
In simpler times people gathered their own fish bait, and a trip to the fishing hole started in the garden digging worms or walking grassy fields to catch grasshoppers.
These days most folks are too busy and just go to the bait shop. But particularly if you have kids, hunting for bait can be a fun and learning experience, putting them more in touch with the natural world.
Gathering your own also allows you access to bait not commercially available. Here is a short list of some bait you can find locally.
