Would you like to get into SW MO and NW AR on your way to Tulsa?? I would, and here's how I'd do it.
Hit MO 65 outta Springfield and go south to Ozark, MO. Plan to arrive there about lunch time and have a feast at Lambert's Home of the Throwed Rolls, on the east side of 65 at MO14 (should be plenty of billboards to get you there). After my nap in the parking lot (
), I'd head east on 14 for a short ride over to Sparta and take MO125 (a really, really nice lean left/lean right road) south and rock-n-roll down to the flat-topped ferry across an arm of Bull Shoals Lake - continue south to AR62 and turn west on 62 and take that to and thru Eureka Springs - I might stop to be a tourist - on over to Rogers/Bentonville, AR. In Bentonville, a nice stop to shake hands with some friendly folks at Bentonville, BMW. Then head on west into OK and generally go NW to Tulsa, or take 71 outta Bentonville and run north up thru/nearby Neosho, MO and hit I-44 at Joplin, then west to the state line and finish up with the toll highway (~350 pennies) into Tulsa. Speed limit is 75 - zero tolerance - on I-44.
If you don't catch any of this on your way west, maybe catch some of it heading back to St. L. Ride safe - have a ball.
