Something very rare will be happening over Casper in late December and it won't happen again for another 60 years after that. Jupiter and Saturn will be closer than they've been in nearly 400 years.
If you are a fan of looking up into the sky and seeing the other planets, then you may want to invest in a telescope because Jupiter is going to be so close to the earth that you'll be able to see it with a pair of binoculars!
