A resident of the St. Streets area reported hearing a loud boom Sunday morning.

User "Lepry" posted to Reddit:

Did anyone else hear a loud boom or explosion in the St. Streets area around 6:30 a.m. today (10/18)?

The time is approximate, but I woke up around 6 and had been up for a little while when I heard it. It sounded like a canon being fired--VERY LOUD. hard to tell which direction it came from--i'm on St. Thomas Street near Souvenir Gate.

One of the commenters asked if it may have been a transformer blowing, which is possible.

I wasn't in the area that morning; did anyone else hear anything out of the ordinary?  Do you have any idea what it could have been?
