I live in Illinois, but have spent a fair amount of time in Wyoming and also Colorado. The University of Colorado Medical Center is a center of excellence for cancer treatment, and might be a better option for you than going to Dallas. Here is a link to their website:

My other question is have you had genomics testing or a decipher score done on your pathology? If you have low risk cancer, you might be able to go longer without treatment than if you have high risk aggressive cancer. My testing came back with very aggressive high-risk cancer so my decision for treatment made itself.
