Okay, after riding the route today, we've made some minor revisions. Less slab!
Roads look good. Traffic was mild to non-existant most of the time. I only had to pass one car and was keeping a decent clip the whole time.
George has suggested a less slabby route from Saginaw to Bridgeport (hooray!
).
The stretch from Boyd to Cottondale to Bridgeport is pretty fun. Some loose gravel on the other side of Cottondale, but nothing too hairy.
920 south from Bridgeport to Weatherford will be a hoot if we don't get stuck behind any slow pokes (like I did a couple times). Passing zones are limited due to lots of hills and curves (the good stuff, right! [moto] ).
Maybe lunch in Weatherford. Depending on timing, otherwise head east back to Lake Worth following 730 and 1886 (those are a hoot and was somewhat reminiscent of the Austin area).
All this is reflected in the original post. But here's a link to Sunday's route.
