Looking at the Portland Winterhawks schedule, I see the following games of note:
Saturday Febuary 4th: Everett vs. PDX
Friday Febuary 10th: Seattle vs. PDX
Sunday Febuary 12th: Everett vs. PDX
Friday March 3rd: Spokane vs. PDX
Saturday March 18th: Seattle vs. PDX
The most expensive tickets are $20, and the cheapest are $7. Cheap live sports, and we can help build the PDX vs. Seattle area rivalry.
