Then, south of Waco, the Interstate is under construction and has been for years. It didn't stop most drivers from driving recklessly through the area.
Once I got to Georgetown, I got on the toll road to bypass the traffic nightmare that is Austin. It was a good move, as Austin was facing far heavier rains than San Antonio. It was something seeing sheets of rain sweep over the road, sometimes the waves were higher than the car, but the water on the road was never too deep to pass.
