Healdsburg, Vaux’s Swifts at Rio Lindo Academy. Saturday, Sept. 14. We hope to see 1000’s of swifts enter a chimney on the grounds of the Rio Lindo Academy. This has been an annual occurrence since 1989, when human use of the chimney ceased. Be advised that we will be returning home after dark. Carpool leaves Sunvalley at 4 PM. Take I-680 across the Benicia Bridge. Go west on I-780 to I-80 towards Sacramento, exit to SR 37. Follow SR 37 to Lakeville Rd; turn right. In Petaluma, take US 101 N to Healdsburg, exit at Old Redwood Hwy/Healdsburg Ave (Exit 502). Go north to Bailhache Ave, turn right on Bailhache, which becomes Rio Lindo Ave. Follow it about 3 miles into the Academy’s main entrance. Turn left at the first stop sign, and another left just before the dormitory. In half a block, turn right toward the rear of the campus, park on the right past the chimney. Bring folding chairs, a picnic supper and join many others as we enjoy the evening show. Alcohol, including wine, is not permitted on any school property in the state. The carpool will first stop in downtown Healdsburg for a bathroom/coffee/food stop. Please call leader if you want to carpool. Note, there is a $10 entrance fee per vehicle at the Academy.
