Where: Hayes Valley Farm, 450 Laguna Street (at Fell)
When: Sun., April 24 to Fri., April 29
The rundown: If the thought of contending with the crowds at San Francisco's Earth Day party on April 23 makes you feel weary and old, celebrate in a mellower vein at Hayes Valley Farm. Starting this Sunday, the much-loved urban farm site has a week's worth of earthy events planned, including workshops on vermiculture and general composting, a fruit tree sale, potluck dinners, "bike-powered smoothies" (?), and much more. Check out a full schedule of events at the farm's website.
