Go ahead and put a big red circle around August 21, 2017. On that day, there will be a major solar eclipse and it's going straight over Idaho.

Here's are the details from Space.com:

As it traverses the United States, the total eclipse will be visible within a path of darkness stretching from Oregon through Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina and finally South Carolina. The path will average 67 miles (108 km) in width, but it will widen to a maximum of 71 miles (114 km) while moving through western Kentucky, about 12 miles (19 km) northwest of the town of Hopkinsville (population 3,000).

I can't remember the last time there was a solar eclipse that was not only visible in the US, but in a path that goes right over us.

Since we have a year to plan, now might be the time to ask for that telescope you've always wanted for Christmas or your birthday. Oh, and don't forget to included the solar filter. Awesomeness.
