Pacific Northwest Mopar shows 2013
9/14 Mopar Summit Portland OR - sponsor??? = Columbia River Mopars
In Portland the Chrysler R/T Car Club normally sponsors one. I have yet to see a listing as of yet.
Here is a listing of area events focused mostly on the Portland area. Still kind of small and new ones added all the time.
