It's probably not too soon to start planning next summer—specifically, the complete solar eclipse that will be visible in parts of Oregon on Monday, August 21, 2017.
It's the first solar eclipse in which the totality will be visible in Oregon since 1979, and the first one to hit both American coasts since 1918. So yeah, it's going to be a pretty big deal. Also, the next one in Oregon won't happen until 2108, and I just checked and you'll be busy then. So don't miss this one. The eclipse's path is indicated in the map above; note that Portland does not fall in the path, although the eclipse will be partially visible from the city. You'll need to go south in order to see the moon completely blot out the entire disc of the sun, and hotels along the trajectory are already selling out.
Despite the early onset of fall that we're currently experiencing, history suggests it's pretty likely that August 21, 2017 will be a clear day without much in the way of clouds, at least for much of the state. That gives Oregon a great opportunity to observe the solar eclipse. Totality will begin around 10:15 am or so (depending on where you are in the state) and will last just over two minutes.
But prime viewing locations in places like Newport, Lincoln City, and Madras will be hot commodities, and traffic will probably make them hard to get to on the morning of the eclipse. The top of Mount Jefferson in particular is likely to be a phenomenal place to be, but I feel comfortable saying lots of other people will have the same idea. It's not a crazy idea to start planning how you're going to view the eclipse now.
