This a huge problem in the warmer places like Florida. People lock their kids and pets in cars parked in lots while they go shopping. 90F outside temps can rise to the 120sF inside a closed car left in the sun. It can also result in the permanent brain damage or death of children and pets. So, this should be taken very seriously. The next time you’re on a ferry and you see something like this, contact the officer on deck and report the situation immediately. If you can’t find an officer, then grab a deckhand and make sure they report it to their officer. Southerners like myself know about these things. I’m not sure if people in cooler climates are aware of the seriousness of this yet. But it is always serious when the ambient temps are over 85F and there is no water or fresh air available to the victims. You saw suffering and you did something about it. Bravo. You comforted the suffering.
