You mean east over by Cascabel? West of the Rincons is Saguaro national monument. There were 6-8 hogs that escaped some years ago over by Cascabel but all were trapped or died. USDA was involved in that as well. They just can't take the extreme heat we have here. They last for a little bit and die off. No mud to wallow in, etc......There have been reports of hogs westt of Tucson, west of the Rincon Mountains. I've heard it a few times but can't verify it.
