December 2019 Meeting Announcement

Our next meeting will be the annual party on THURSDAY, 12/5, at 7pm at the Black Bear Diner at 415 E El Camino Real, Sunnyvale (just North of Fair Oaks Ave). All of our meetings are public and everyone is invited. We will have a Yankee gift exchange; if you want to participate, please bring a small gift that a fellow microwaver might enjoy or use, perhaps something neat from your junkbox. Hide it in a bag or box, so we can't tell what it is (doesn't need fancy wrapping). Those who bring gifts will choose another gift in exchange, and then the fun starts.
