I went on a prairie dog hunt about a month ago on the Standing Rock Sioux Reservation that covers both North and South Dakota. Lots of dogs, but I would be very carefull who you hire as a guide.
Had major problems with one of the guides that starting raising hell with us. Tried to say we were tresspassing on his land while we were on tribal land that was open to everyone with a license.
I wont go into details, but its safe to say it left a very bad impression with all of use that were involved. Hopefully that is not the norm up there, but I dont know if happens all the time or not.
