MARFA - If you're interested in something a little more mysterious, you'll want to check out the Marfa lights festival.
Starting Saturday, visitors from all across the country head to Marfa to catch a rare phenomenon known as the "Marfa Lights."
They're glowing orbs that seem to float in mid-air.
No one's figured out exactly what they are.
The festival's been going on for 25 years.
There will be a street dance, parade, booths and all kinds of food.
It will all be centered around the historic Presidio County Courthouse.
