…and you’ll glow? Clearly, Vanilla Ice does, and you can too - with eco pride - starting 8:30 pm tomorrow. Once again, SF’s getting in on World Wildlife Fund's Earth Hour 2009, bringing worldwide attention (from Rio to Dubai) to global warming. Just flip your light switches off from 8:30-9:30 pm - and check out iconic spots like Union Square, City Hall, and the Golden Gate Bridge doing the same. Plus there’s City-sponsored events for you to get in on, like weeding at the Corona Hilltop Restoration with SF Parks and Rec from 10 am ‘til noon, or planting 60 trees in 60 minutes with FUF at 8:30 am in the Presidio. Word to your mother (earth).
