The Border War between Colorado State University and the University of Wyoming is one of the most storied and intense rivalries in the Mountain West Conference.

JAX Outdoor Gear wants to send a pair of Rams and Cowboys fans to the 2019 Border War showdown in style for the latest JAX Outdoor Adventure.

CSU and Wyoming fans have been submitting photos of their school spirit all month in hopes of winning the Border War grand prize. We narrowed it down to the 10 best on both sides.

Now it's up to you to decide who goes and wins the adventure. View the photo galleries and vote for 1 Rams fan and 1 Cowboys fan.

Whoever has the most votes by noon on Monday, Nov. 18 will win a pair of tickets to the game plus $150 in prizes to each of the four attendees, including KUHL clothing, a YETI Rambler Colster and a YETI Rambler Tumbler. People can vote once per hour.
