No, seriously, it's a school-sponsored trip for his art classes. He'll be back Saturday at 9pm. The schedule is pretty tight; they only have a total of 2.5 hours in two segments of free time. I wanted to take him to New York in December, but ran out of money and days off. I suspected this was going to happen, so when his school arranged for this trip, I said, "Yes!"
I hope he has a good time.
