None of the clothes were going to work, tho, so we went to Kmart, where we found a poly hoodie and some poly pants with enough thickness to maybe be warm.
At home, I found the dry bag backpack I've never used (bought to take to a Disney waterpark, but we still haven't been to a waterpark *shrug*), and put the hoodie and his rainjacket in it, along with sunglasses, a hat, a set of small binoculars I've had since R. and I did our through hike in the Olympics. T. and I went to Subway to pick up a kids' meal for his lunch tomorrow. R. got out a couple water bottles. I think he is Ready To Go. On previous trips, he has been distressed with the rules (closed toe shoes, type of thing) and this set of rules is by far the most detailed, but for whatever reason, he was very on board with just going down the list and doing it all. And he even understands he has to get off one bus and onto another when he gets to school, so he can't do any of his morning routine at school (wash face, brush teeth) but must do it at home instead.
Good news: after this shopping, he's all set to go hiking or orienteering, which is pretty cool, too.
