Definitely no excuse

My kids survive Arizona summers where outside is 115 and inside is upwards of 200 when parked.
I have something similar to
this that I bring with us when we'll be out for the day.
I also start the car before leaving just as you would in the winter to defrost and I point the air vents towards the ceiling to help with circulation. My FF is just as sweaty as my RF in the summer. It's hot and there's no way around it..might as well make sure they're safe!
