Number observed: 1
Details: Heard for perhaps 20-30 seconds as it flew past heading SSE. A repetitive (monotonous?) nasal honk, one roughly every two seconds for the entire time. Because of woods on both sides of the road, we only had a view of the bird for a couple of seconds as it passed over the road at some distance ahead of us. A goose. My wife has better eyes and she saw some white. No optics. Overcast and a little bit of fog so visibility not the best, but sound was very clear.
