I own a 1-acre pond, but its about an hour drive from my house, so I haven't fished it in 2 years! There's no crappies in it.
However, the pond I fished this weekend is a public pond that is just a few blocks from my house. Since its a public pond, I release all the fish and USUALLY use flies with barbless hooks, to minimize damage to the fish.

A lot of neighborhood kids fish the pond, and most kids don't care how big the fish are (me neither, they're all fun), so its one of those places you just want good numbers of fish.
