If you haven’t noticed by the number of young women getting their nails and hair done, it’s prom season on the mid-Peninsula. Menlo-Atherton High School’s prom was last weekend, so what was this huge stretch Hummer doing on a Menlo Park street earlier this evening? After a thorough bit of investigative reporting, we found it was waiting for couples headed out to the St. Francis High School prom. The girls all looked fabulous and the boys, well, looked like boys. And a safe time, we trust, was had by all.
