Hey MJN... where you at in the Tri-Cities? I lived there 18 years and moved away in 2003 to take a position at Oak Ridge.
We lived up in Rancho Reata, so your first picture looks very familiar. I never rode until I got to TN, but, I used to take my Testarossa down the old highway from about Hat Rock State Park down to Pendleton. The road is pretty twisty for the first half and then there are some nice straights you can open it up before coming into Pendleton.
BTW, I-84 between Clodfelter Road and the Richland connection with I-182 is a pretty good place to open it up. I've seen 160+ in the Testarossa on that section of Interstate. A Valentine One will let you know if it is clear.
