Dave, to my point that still is a whole lot of going East to spend the night in Greely to go back West to Woodland Park.
Edited for additional information: After looking at your route Dave, I just question if KKL would have traveled 1-40 considering it's a smaller highway that skirts along some of the ski resorts (Winter Park & Steamboat Springs) steep elevation and winding mountain passes. If she were coming in from that side, the West, I would think KK would have zig zaged over to Breckenridge by way of HWY 9 South to Fariplay where it hooks up to 285, that spits you right out onto HWY 24, which is the main road going East to West through Teller County (Cripple Creek, Woodland Park, Divide, etc) this would be a familiar route to her, IMO. Like I previously said, I personally would have driven South of SLC on HWY 15 all the way to I-70, through Grand Junction (this is a much flatter drive) and then the above route that I stated. Unless she had plans to stay with someone in Greeley, I see zero reason to travel that far East for the night. Maybe she missed her turn?
