Chris, I think the answer you're looking for is yes, you can compete in any tourney you'd like. When a tournament is PDGA sanctioned, those that are not PDGA members usually have to pay an additional fee for entry, which goes to the PDGA. All PDGA sanctioned events have a tier designation - in the case of the Girdwood tourney it is a C-tier. Larger events that have more added cash to the pro pot could be classified as a B-tier or even an A-tier. A-tier events are generally in large markets that will draw a lot of touring pros due to the additional added cash. Hope this answers your questions!
