Mellow Yellow is a head shop that famously opened in 1969, but in 2020, it'll finally be time to say goodbye.

According to the Coloradoan, Mellow Yellow was the first head shop in Colorado, a historic opening in its time. The owner was Jerry Weintraub, who says that thanks to Fort Collins' booming resident growth, costly repairs on the over 100-year-old building, and competition from local shops, he's decided to finally sell his long-standing shop.

If you were a fan, you can still visit Mellow Yellow's Greeley location at 837 16th Street after the Fort Collins location closes on January 1.
