Grand Coulee Dam, WA

The Grand Coulee Dam, while not as tall as the Hoover Dam, is actually 4 times larger.

Every night, when the sun goes down, they have a laser light show.  Starts out pretty cheesy, but gets better

I drove south from Grand Coulee Dam, and since I waited to watch the laser show, it was dark while I was driving.  I ended up staying at a rest area at Blue Lake, and when I started driving again, I thought I may have skipped a few States in the dark...it didn't look like Washington anymore
