I just checked the MySpace RHS forum for the first time in months, and apparently the Class of 1987 had their 20-year reunion on June 1 and June 2. (UPDATE: That forum link doesn't seem to be working at the moment, but you can see the forum here.)

They were looking for missing persons on MySpace in April. And they are using Reunions by the Party People like our class did for our 10-year, so it's probably safe to assume they'll be handling our 20-year reunion as well.

I notice the ticket fee is much lower if you pay early, so if you're thinking of coming to the Class of 1988 20-year reunion you should plan to buy tickets before the end of the school year.
