Well yesterday when I was packing, the weather said it would be chilly Friday night and then warm up a bit and be fine the rest of the weekend. Today it says it will be cold, clammy and maybe even wet all weekend.
I'm so glad I'm prone to overpacking. I did skimp a bit on the rain gear. He only has a trashbag-weight disposable emergency poncho. But he has two changes of pants (one of which is polar fleece), three T-shirts, two long sleeved shirts and two jackets.
I bet he's having a good time.
