The Golden Gate bridge spans the Golden Gate (a strait), not the San Francisco Bay (a body of water, south of the strait and of San Pablo bay, and spanned by the San Francisco-Oakland Bay, San Mateo and Dumbarton Bridges).
for sure you need to fix the Golden Gate bridge clue as mentioned a year ago. also you should accept Mt. for Mount Rushmore. You could also accept Cape Canaveral as an alternative answer since that is the geographic term for where the Kennedy Space Center is located. Otherwise nice quiz.
