Show notes

Good morning! Today Mark Houston gets ready for Rapid City's massive America birthday bash, complete with a 500-drone show launching from Central High School. He digs into WalletHub's ranking of the best and worst cities for the Fourth of July, and he's pretty fired up that the home of Mount Rushmore got snubbed entirely. Plus, you'll find out the truth behind that mysterious low hum people swear they hear all around the world. Turns out the answer might be inside your own head.
