When I was visiting Texas in September (I was born there) there was a 2-33
on tow about 35 minutes SE of San Antonio, near Karnes City. I'm not sure
what operation is near there. If you drive towards Corpus you can stop in at
Refugio, which is about 1 - 1-1/2 hours southeast of SA. Not very active
during the week, but they have a decent fleet of ships.
