Reunited, and it feels so good?

I got an email today about my 15th high school reunion. M and I skipped my (and his) 10th, because they both were prohibitively expensive. But I'm wondering if I should go to this one. It's also homecoming weekend for Syracuse in October (my 10th anniversary was in May), and I'm not sure if I should take a ride up to Central New York.

So which of my readers actually went to their reunions, high school or college? Worth it?
