The Tank, Las Vegas Why It’s Cool: This $30 million pool is the only one of its kind in the U.S.: you can swim with more than 200 different types of fish, including stingrays. Okay, not exactly swim with them. The pool surrounds a 50-by-30-foot, 200,000-gallon acrylic tank teeming with marine life, and a three-story enclosed waterslide tube shoots you through the tank in eight seconds flat.
What's the ONE thing you must do in Texas, according to the Huffington Post? Tube the Guadalupe River! Nothin' says Texas like drifting down the river on a toasty summer day with all your best friends and a massive floating cooler of Coors.
