Learn about everything from the South Texas shrimping industry to the history of Brownsville with this 4-hour cruise. You'll also get a glimpse of Starbase, a rocket factory and launch facility created by Elon Musk's SpaceX. If you’re lucky, you may even spot Atlantic bottle-nose dolphins or migratory birds right from the deck. As an added bonus, coffee, donuts, and shrimp cocktail will be served, free of charge.
