Today is the beginning of several big events in Austin. The biggest are the Star of Texas Fair and Rodeo through March 27 at the Travis County Exposition Center and the South by Southwest Festival through March 21 featuring music, film and an interactive conference at various venues around the city. Of course, this means that the streets, restaurants, shops, etc., are very crowded.
The weather is cooperating this time. There is only a small chance of rain over the week end. This is one of the busiest week ends of the year.
