Scott - right on - happy to contribute.
Dyskord - nice recommendation, too bad no one jumped on that. I agree with you about 290... At least dropping down the extra few miles of 281 to get to Blanco (then to Fredericksburg) is a much nicer ride. Or, if the route does end up touching Austin at all, taking 290 out of town and catching Farm Road 165 to Blanco is another great option. I just rode it a few months back going to the Harvest Classic, and FR 165 is one of my new favorite roads. Not to many miles, but awesome.
Kinda surprised more Austin folks haven't chimed in...
There should be five riders from the Austin area.
Keep in mind, the riders set the route, Scottly, please confirm.
Looks like Coyote will be riding south from Dallas, I plan to hook up w/him just Northwest of Austin, maybe Burnet? [south of Lamasas on 281].
I personally do not care to ride in Austin.
Ranch Road 1431 is fabulous, it runs just north of Lake Travis and Lake LBJ on it's way to Llano [via 29] and one of Texas great BBQ joints - Coopers.
This would be a great area for an overnight camp stop.
I know this area well and am sure it would be enjoyable.
