With so many rainy days in Seattle, it's no wonder they have such a spectacular indoor stadium for concerts and sporting and family events. Located on the Seattle Center grounds, this facility once hosted the 1962 World's Fair and NBA All-Stars Game in 1974. However, to accommodate a larger crowd (and fix a leaky roof) the arena was rebuilt in the mid 90s. Now with seating up to 17,000, visitors can find refuge from the constant precipitation.
