Seemingly endless rolling plains are perfect terrain for the high speed, open country favoring, prong horn.  Clusters of females and their young gather in the grassy folds and lone males dot the higher ground.  I love the challenge of watching for them! 

Did you know, there is a Lincoln Memorial in Wyoming?  It marks (actually used to mark before it was relocated) the high point of Lincoln highway(US 30) at the summit rest area on 80 west of Laramie.  Who knew?
