The shop owner has probably put up a fence designed to control cattle. Let's see, a cow weighs maybe, I dunno, 700 pounds? And the average adult male weighs maybe 150?

I just read a book involving horses, and it was mentioned that a good-sized horse can weigh 1000 pounds. Maybe a good-sized steer weighs that much.

Time to do a little science here before somebody gets badly hurt and the shop owner loses everything he owns.

Read the article, Jim. It says the owner has been taking pictures of the offenders. That's a much better approach, if you ask me.

I also like Stringbean's idea that somebody should be going after the pubs.
