American from Port Angeles here. I've used your video in my English class to introduce where I'm fun. I just want to say there's NO WAY you could get from most of Olympic National Park to Seattle in 2.5 hours. 3.5 hours, maybe.
Aha, I am the first! I will visit Seattle for two days in Sep and I will have one day trip to the Olympic NP. It is my first time visiting the park. So, thank you for your excellent introduction. Btw, I am in TX, hot and humid, so I believe I will enjoy that😀😀.
