I'm sure there are a lots of Pokemon fans in Seattle, sadly I never met any of them.
In my home, my younger brother used to like Pokemon when he was 8 years old (along the way he stopped watching it), I was 14 or 15 at the time. Now, I'm the only one who even like Pokemon in my home, I'm not afraid, or embarrassed to admit, every time I drive the car, I bring one of my key chain plushies with me. At times i wear my Meowth T-shirt (just yesterday I ordered another PokeShirt) - so proud to be Pokemon fan, even if other people give me strange looks on the street.
Sum it up: I"m the only one in my home obsessed with Pokemon, I have not met any other fans in Seattle either.
