It's winter in Tucson, which means sunny days, chilly nights and lots of outdoor fun with friends. 

Meet you at the top of Mount Lemmon to build a snowman!

They’re active in early morning, are found at golf courses.

And no, we're not taking about those animals with the feathers — brush up on your Tucson words here.

Spotting a snowbird also turns into your new favorite game, double points if you see one driving a golf cart on the road.

Acceptable substitutes are Birkenstock sandals and a sweater or Uggs and shorts.

You may already have a fridge stocked full of them thanks to your family's yearly tamale-making party. But in the chance you don't there are plenty of places to help you with your masa and meat needs

11. There's a sudden urge to cheer on the Wildcats.

The raucous ZonaZoo student section has a well-earned reputation for making things difficult for opposing players trying to shoot free throws at McKale Center.

Take at look the UA basketball schedule for upcoming games and 🐻 ⬇️.

It's dangerous work but it's not winter in Tucson without twinkling saguaros.
