Deonte is correct. I can help you out with Utah resources. We have slams in Ogden, Salt Lake City, and Riverton. There is also a CUPSI (college team) at the University of Utah that formed last year. You can keep up on our happenings on facebook at https://www.facebook.com/groups/142817314750/
As Deonte also mentioned, all slam teams are selected through open competition. The two PSi certified slams we have are in Riverton UT at the Coffee Shop (Second Thursday of the month) and Salt Lake City at Mo's Grill (Last Monday of the Month... TOMORROW!). Both are 18+ slams and both just started their seasons. See the facebook group for more info on our selection process, or look up each slam in the selection process threads on this forum.
Ogden has a slam the 3rd Tuesday of the month at Grounds for Coffee, but is not PSi certified and will not send a team to the National Poetry Slam in 2013. The University of Utah has a slam team they send to CUPSI, but you have to be a student to get on the team.
Let me know if you have any further questions, and please check out the facebook group.
