I live in Oklahoma and have driven (a couple of years ago) but not ridden the western half of your requested route so take this as you want.

Coming from Boise City (Black Mesa), I would suggest US-64 to OK-11 (near Cherokee). Continue east on OK-11 to Blackwell. The AADT count is 1600 or less (except for the Guymon to Hooker section which can be avoided with extra miles).

From Blackwell, there are back roads to Ponca City. From Ponca City there is a county road to Fairfax. From there, take OK-18 to Ralston then OK-20 to Hominy. Again, all have low AADT. From Hominy, there are a couple of county road options or you can take OK-20 to Skiatook and then the Osage Prairie Rail Trail into Tulsa.

You should know that Oklahoma unfortunately does not put much money toward quality roads. Also, the above route has many "towns" (more like wide spots in the road) without ANY services between Boise City and Blackwell. If you go in the summer, carry plenty of water and always top off.

Winds are mainly out of the south during the summer. During the spring, you can expect extreme weather with strong winds out of all directions depending on the weather pattern.
