Andrew (14) and I spent the last three days camping at Spencer Spit State Park on Lopez Island, which is in the San Juan Islands north of Seattle). We had never been the Lopez Island before; we found this park through recommendations from friends on Facebook (search really is better with your friends...) Aside from a huge downpour that started right after we set our tent up, the weather was perfect -- sunny and warm.
We tried our hand at sea kayaking for the first time. We launched from the south side of the beach and circumnavigated Frost Island. We managed to successfully stay dry until a fell on my ass getting out of the boat, soaking myself in the process.
We spent a lot of time on the beach. Andrew loves driftwood beaches; he's always making stuff. Knowing this, I brought along some paracord (always useful and good to have around). Andrew used the paracord to fashion a hoe, chiseling holes through a shell and tying it onto a driftwood stick.
The shells made nice targets for our new slingshot, which we tried out for the first time. They exploded in a very satisfying way when hit, although we didn't manage to hit them directly too often since we were still learning how to aim the shots.
We also used some shells to boil seawater, in an experiment to harvest salt. After boiling off the water, we did manage to get a little salt in the bottom of the shells. I think we'd have to keep adding seawater to get enough salt to scrape out. Note: the shells can pop and explode, I'm guessing due to pockets of moisture in the shells. Andrew got hit by a "shell fragment".
Beyond our beach adventures, we played with a night-vision scope, which was much more fun in the woods than at home. We even watched a doe for a while through the scope. She didn't notice us (or didn't care) so we got to watch her feeding on the trail for a while. (No photos of this, unfortunately.)
Our campsite (#2) was pretty good. It got sun for a good part of the day and was conveniently located to the water, garbage, and restrooms. It was OK private, but a little noisy from the nearby group camping sites (although I'm not sure any sites would have been quieter). The park has a few walk-in camp sites on the beach, which would have been fun to try, although they're not very private and use a composting toilet instead of the nice clean flush bathrooms servicing the other parts of the campground. (They do have a cart at the parking lot to help you bring your gear down to the site, however.) It's also worth remembering that you can buy firewood at the campground for $5/bundle. (The "camp hosts" will even deliver it to your camp site); bringing enough firewood is always a hassle, so this is a nice perq, although I don't know if they have this service year-round.
We both really enjoyed the campout (and the visit to Lopez Village). Andrew kept saying "this is the life" and thanking me for taking him along. It was definitely a trip I'll always remember.
