I don't think I can sum it up any better than the title says. Right here in Texas, in Houston to be exact, you can take a ride on train that literally goes through the aquarium. You are actually going right through the middle of a glass tunnel in a 200,000 gallon fish tank, and the sea creatures swim all around and right up to the glass next to you. They call it the "Shark Voyage Train".

To give you an idea of what it's like, check out the post from the Aquarium Houston Instagram account:

Do you realize how cool that is? You get to be right up close to the underwater world, seeing all the fish and stuff, all while riding on the train. I don't know about you, but when I was growing up, two of my favorite things were fish and trains. Now I'm an adult and I find out that those two things are in the same place, at the same time. I'm sold.

Plus, it's in Houston, so the drive isn't that bad to go take advantage of a really cool attraction. I'd make the trip to Houston for the chance to ride the train through the aquarium in a heartbeat. And ticket prices for the aquarium aren't unbearable, either. It costs $14.99 for adults (people 42" and up), and $11.99 for children (people under 42"). Then, the tickets for the "Shark Voyage Train" are only $5.99 each. See? They're not too bad.
