Well, we actually did get out of the house the entire weekend!  On Saturday, we went to Mount Saint Helens National Volcanic Monument.  We went in on the west side of the park, stopping at the Silver Lake Visitor Center first, then working our way up to the Johnston Ridge Observatory and over to the Coldwater Ridge Visitor Center.  (With a few stops at scenic spots along the way, of course.)

The Little's favorite parts of the trip were the fox pawprint stamps she got on her hand at the admissions booth and the video of the 1980 eruption shown up at Coldwater Ridge.  We only watched the show twice this visit, but in the past she's watched it (in one sitting) more than a half dozen times!

Here's the view of Mt. St. Helens from the Johnston Ridge Observatory:

And here's the view further up Johnston Ridge, including part of the memorial to those who perished during the eruption on 18 May 1980:

This is a pretty little waterfall we spotted across the road from a scenic turnout we stopped at.  We had a guest along this time, who was originally driving my truck...we stopped so I could drive and let him just enjoy the view!

For reference, I highly recommend that traveling homeschool families invest in a National Parks pass and the Golden Eagle hologram to go with it.  These two will get you into any National Park Service sites that require an entry fee, as well as sites managed by the Bureau of Land Management, U.S. Fish & Wildlife Service and the U.S. Forest Service.  At $65 (combined), this pass can save a family of three quite a bit of dough, let alone a larger family.  (Go check out those links too; they have plenty of interesting resources for kids and adults!)
