Each class is responsible for sending out their letters to their classmates. Our goal was to have all the letters mailed out by the end of March. I am from the class of 1977 and our letters went out several weeks ago. My husband is from the class of 1975 and they are still working on getting theirs mailed. I am not sure about the class of 1976 but the All 70's Committee meets in a couple weeks and I will ask about it there. Since your class just had a 30th last summer - I don't think it will take much to get a letter mailed out since the work of finding addresses should be done. Keep checking your mailbox - it should be coming soon.
