We all have weird traditions whether it be yourself or where you live. What is Montana's weirdest tradition? We now have that answer.

Thanks to MSN, a list of the Weirdest Tradition in Every State was compiled and for Montana it's one of a kind at a one of a kind event.

The tradition is the Undie 500 at the Montana Testicle Festival outside Clinton, Mont.

This five day event brings in over 15,000 people, all 21 and over and has several events like eating some Rocky Mountain Oysters, but the Undie 500 stands out.

The competitors strip down to their underwear and races tricycles. It's been happening since 1989 and shows no sign of slowing down.
