This year I plan on taking 10 day to 2 weeks to do a similar ride. So far I'm considering the Pony Express (2000 miles one way 4000 total) the Butterfield Overland Mail Stage (3750 miles one way 5750 total) or around 3 of 5 Great Lakes (3500-4000 mile total).

I would really like to to the Butterfield route but going through OK and West Texas in the summer does appeal however, once pace West Texas I'm be in parts of NM, AZ and CA I have never seen before.
The Pony Express has a lot of history that I am very know pretty well. The route has a lot of remote traveling that I like and it goes through some areas of the country I have never seen mostly past Salt Lake City. Drawback is summer through KS, NE and the desert of Northern UT.
Around the 3 Great Lakes (Heron, Ontario and Erie not Superior or Michigan because I have circled them in the past) appeals because of cooler weather in the summer and much of the Great Lake history will be new to me. The draw back is the majority would be on blacktop and the urban sprawl especially along US side of the Lakes.
Do anyone have any other thought as potential rides? Any comments on the rides mentioned?
