2019 Winterfest Classic (Learn to Curl!) at BOK Center You can sign up as a team or as an individual but once the available spaces are gone, they're gone. If you're wanting to play, $25 guarantees you two one hour matches. Registration is open over on the website so go get signed up before it fills up! You must have prior curling experience to play in the friendly matches. Also happening, is the Learn to Curl event. It runs all evening and is FREE of charge. No registration necessary...just show up. Grab a friend and invite everyone you know out to watch the matches and get on the ice for some hands-on curling experience! This is a good way to get familiar with the game and interested in our instructional league happening during the month of January.
