If you've ever driven on I-70, through Genesee in Colorado, chances are you have seen the bison herd that can be on the north or south side of the interstate. Folks that drive that route, look for them every time they pass through.
The workers at the park have been trying to increase the herd size. This spring they welcomed two dozen new calves, with more to come. There were 33 bison in the herd, and every spring 19 to 20 calves are added, but this year they are expecting a little more to increase the herd.
