Discovered there must have been an airport right next to our island parking spot. Low flying loud planes passed almost overhead. The trains were also nearby and rumbled noisily. Both stopped by around 10 pm. The automobiles however with their noisy passenger started partying around 11:30. Their party was over by 12:30. Good thing we could stay one night! Off this morning towards Niagara Falls.
Tip: Try to anticipate possible nearby nighttime activities.
