Jays fans very much made Safeco Field the SkyDome of the West, home away from home. In fact, Jays fans vastly outnumber Mariners fans in Seattle for the series! This cannot be said for any other time the Jays are on the road.
Mariners fans complained about Jays fans "invading" their home territory. Much more fans cheered for the Jays than the Mariners in the latter's home field even. Even the border guards were bewildered about the large number of Jays fans from British Columbia (primarily from the Vancouver area, given how close Seattle is to Vancouver), some of whom wear parrot costumes (to cheer for Edwin) or rain jackets (for Donaldson).
Go Jays go!
