My office mates and I had a company team building thing yesterday where we took and hour or so and walked up to that big-ass satellite dish behind Stanford. It was quite the trek - I'm so out of shape that the hills about killed me and I stupidly wore new sneakers and got a blister. But it was a nice little trip. In theory it'd be a great thing to start doing often as I work just down the road from there and the trail is really nice - great views!
And yes, my hair is getting grey to the point of being white, especially in the sun. I would have smiled in the pic, but my foot hurt.
