Since the Medicine Bow NF now includes northern Colorado's Park Range on the west side of North Park (and east of Steamboat Springs) (the former Routt NF) and the Flat Tops, you might be in northern Colorado.
It's a very large and spread-out national forest and includes the Laramie Mts. east of Laramie, WY, the Snowy Range about 30 miles west of Laramie, the "Sierra Madre" range west of Saratoga, WY, northern Colorado's Park Range (north and east of Steamboat Springs), and the Flat Tops (southwest of Steamboat Springs). The Thunder Basin National Grassland is also under their jurisdiction.
Did they say what ranger district you'll be assigned to?
May your trails be crooked, winding, lonesome, dangerous, leading to the most amazing view--E. Abbey
