They’re calling Saturday “ZIP Code Day” in Claremont, when its 91711 ZIP code will become literal on 9-17-11. An overview of the day’s multitude of events will appear in my Friday column. Here’s the link to the Celebrate91711.com website with a full calendar of events — and there are a lot of fun ones, especially a community photo at 5:30 p.m. in front of the Claremont Depot.
