I have a sister that lives near Casper ... I have personally driven numerous times on all of the roads I will mention in this post. Basically, Medicine Bow is one of the windiest places on earth
http://www.4j.lane.edu/partners/eweb...windpower.html but not really all that scenic IMHO (not compared with what I've already got in and near SLC!) If you really want to detour from I-25 and have an Old West experience, you could swing over to Laramie on US 287 (leaving I-25 at Fort Collins EARLY IN THE MORNING). Then take US-30 out of Laramie going north until you get to Bossler Junction. Then take Wyoming Highway 34 going east. This road will take you through some nice mountains and also through a wildlife refuge, which has a visitor's center that you can stop at and visit (during summer months). Highway 34 will take you back to I-25 about two miles south of Wheatland.
Once you are back on I-25, go into Wheatland and then take Wyoming Highway 160 east to Fort Laramie, which is a National Historic Site
http://www.nps.gov/fola/ and VERY INTERESTING. Then take US Highway 26 west and stop in Guernsey to see the Oregon Trail Wagon Ruts.

From there, take Wyoming Highway 270 north until you get to Meadowdale. You have to watch VERY CAREFULLY for Meadowdale or you will miss it, since there is nothing really there other than a turnoff onto Meadowdale Road, a graveled road that will take you past my sister's ranch to Glendo State Park.

At the state park, there is a paved road that takes you into the town of Glendo, which is on I-25, and you can then go north to Casper. (Or I can give you further things to do on the way there, if you want ... there is always the Spanish Diggings
