Yes this is a wonderful project.

Neat how he is raising the fish in the greenhouse too.
I LOVED that idea. Even just raising bait would be an added money maker - minnows or red wigglers. :)
Some nights out in the yard, with no help from me, we have night crawlers as long as your arm. They’d bring a pretty penny.
