This White-tailed Prairie Dog colony used to be easily visited at an I-80 rest area in Sweetwater Co., WY. The animals have since been removed by highway officials since they considered the prairie dogs a rabies threat to pets at the rest area or so I have been told. This is the same area as the iNat record at:

but several weeks later. Image 4 shows a pair mating.
