Why does Manteca — a city of 73,000 – still have a library that was designed for a community of 36,000?It’s the same reason it doesn’t have a dog park.There is no well-organized grassroots effort to keep pressure on the powers that be to make either happen.You may disagree with the need for a dog park if you’re a library booster. And by the same token you may think a dog park is long overdue if you’re a canine fanatic. But that really isn’t the point.Manteca has neither additional library facilities nor a dog park because simply wanting either isn’t going to make anything happen.There have been periodic pushes for new library facilities since 1992.
