UPDATE: The dog involved eventually passed on later today at the vet. Please keep the family involved in your prayers. Rest in peace Odin.

Today, an incident occurred at our fuel dock when a boat exploded and caught fire. Our staff and first responders acted quickly, and two individuals and their dog were safely pulled from the water. We are relieved to report that they are okay.
It was reported that a pet had been lost in the incident, but we can confirm that the dog involved is alive.

We are grateful for the quick actions of everyone who responded and for the support from our community. Just a reminder to be mindful and practice empathy when commenting about something so traumatic.
