corporal punishment in US schools

I have been living in the dark. I had no idea about how widespread *legal* corporal punishment was in the States and particularly in the South. Strange how this map looks like something out of the 1800s. No wonder northern VA has adamantly against being associated with "the South." If you thought the differences had narrowed, think again.

What do you think? Is it a good idea? I think if you think its a good idea - do it at home.
