Well, we have several Leagues in the Denver area.
What part of Denver are you moving to? There are two pretty active Leagues in the North area of Denver, one on the East side, one on the West, and one in the South.
I own one of the North Leagues and help run the other North league.
Let me know when you are heading to and I can get you all the information for the ones near you.
PM if you want.
