The closest one to you will be the Show in La Grange in March, they also have one in conjunction with the Fair in September.
There is suppose to be one in New Braunsfel in March but I have yet to hear or see anything about it. I am sure they will post something when they figure it out.
They have moved the South Texas Fair to March also - it is in Beaumont
The Bluebonnet Classic is January the 3rd in College Station. We are hoping for it to be around 800 birds like last year.
These are the only choices you have for south or central Texas. Most people are not lucky enough to have a show real close by and will have to drive somewhat.
For the record I am at a show right now in Shawnee Oklahoma.
