Ok... tweaked my route to look more like this one. We'll give that a try tomorrow. However, on the way back, since this route runs through New Waverly, I can run a bit more on 150 and catch 1725 back to Cleveland. that's a lot better road than some of those on the way back from Conroe. I'll probably just slab from Cleveland to 1960 from there...
it looks like the "little sisters" roads are the "around the lake" roads that I have in nearly all of my routes... I know those well!
