Seems like they have good intentions but what they are doing is bad. In APBTs BYBers are what I call "Yard Breeders" They have a yard of animals tied up on chains. The thing is a springpole. Niño does the same thing off of our disk swing. I'm being driven crazy by that site's unessesary use of appostraphies!
Here's a good link about springpoles http://www.workingpitbull.com/springpolegallery.html
