回複：剛才在後院焚燒樹葉，引來了警察和救活車，給了我一張卡片，寫

根據加州的法律，您可能不可以在自家院中燒樹葉
Beginning on January 1, 2004, no household trash or garbage can be burned outdoors at residences. Dry, natural vegetation, grown on the property, can still be burned outdoors in open piles, unless prohibited by local controls. Burn barrels will not be allowed for burning waste, including vegetation, at residences. During 2003 local air districts will determine if there are any exemption areas, with extremely low population density, where dry, non-glossy paper and cardboard can still be burned, and where burn barrels will be allowed at residences.
