Pocket Gophers????

[ACPOSSETIM]

Has anyone heard of these? A buddy and I were looking at a farm we are thinking about leasing in WI and while driving through one of the farmers fields he said "man those pocket gophers are even up here".....both of us kind of looked at eachother like.....what the heck did he just say? I asked him if he meant groundhogs, and he said no but from what he described they sounded like prarie dogs but he said no. Does any one have any ideas or pics? Thanks
