When Is The Best Time To Visit Washington State

I am looking for the best time to visit Washington State. I am wondering if there is a specific time of year that is better than the rest for visiting Washington State. I am looking for a time of year that will offer the best weather, activities, and scenery. I am also looking for a time of year that will be less crowded and less expensive. I would love to hear from people who have visited Washington State and what their experiences were like. What time of year did you visit and what did you like most about it? What time of year would you recommend for a visit?
