Admission to the Texas State Aquarium typically costs about $35 for adults and around $25 for children.
But on Monday, admission will cost just $2 per person.
The Navy-Army Community Credit Union is hosting a $2 Community Day on Jan. 20, which is also Martin Luther King Day.
The reduced admission tickets only are available on site that day.
You won't be able to buy them in advance or online.
The $2 admission fee will give you access to all the aquarium's exhibits.
But parking in the aquarium's lots will cost $5 per vehicle on that day.
