When I go forth aminnowing I go prepared. I have a 10' (diameter) cast net with 1/4" mesh and some minnow traps...painted green (that works better). I use a mix of cheap dry dog food and leftover stale brown bread in my traps. I also take one or two light rods with some special small "chub jigs" that I bait with a pinch of worm...often fished 3-5 feet below a bobber in weedy ponds.
With changing land ownership, DWR's vendetta against chubkind, varying annual precipitation and other factors it is getting harder to find any spots with minnows that minnowing is allowed.
If you truly wish to become enlightened in the ways of the minnow I would be happy to help you in your quest to become a chub (Jedi) knight. May the slime be with you.
