A quarter-acre fire on Vision Road in Inverness was extinguished early Friday morning by crews from Inverness and Marin County Fire. The slow-moving fire was sparked by a power line that was knocked down by a fallen bishop pine. PG&E reported the fire just before 2 a.m. after responding to a report of an electrical brown out; the blaze was extinguished by 5 a.m.   David Briggs
