Now that would be a nice ride...Texas Winery tour.... couldn't sample much though!
You know, that's a great idea.

There's plenty of wineries in this area with great roads to boot. I'll look at how to put together a fun route.
By the way, Sister Creek Winery was not shy with their tasting pours and after the first two wines I was just sipping only the tiniest amount and then pouring the rest out.

In Gruene we had another tasting only after a big dinner at the Grist Mill...nevertheless, a limited number of winery stops per day would be best!
