OId Fort Stevens on the Oregon Coast

Fort Stevens was built during the Civil War, although exactly what it was supposed to defend America from at that time isn't entirely clear. It was named after Isaac Stevens, an important general in the Union Army who got himself killed during the Civil War. From the Civil War through the end of World War II, Firt Stevebs defended the mouth of the Columbia River, but eventually it became obvious that submarines could do the job much more effectively. It has since been converted into a pleasant 2800-acre Oregon State Park. You can still see some of the gun batteries. I think the Japanese once lobbed a few shells at it, but otherwise it had a very peaceful existence during all those years. It's even more peaceful now, with plenty of camping spots. There's also a KOA across the road, if you prefer that kind of Kamping.
