My mom has been dealing with a bunch of health issues lately so I've been spending a lot of time driving to Iowa and Chicago. If my ears aren't ringing and my voice isn't hoarse after those 4 and 7 hour drives, I haven't been doing it right.It's fairly low volume when we're both in the car, but when I'm driving by myself, it's Katy bar the door...full volume with me bellowing along at the top of my lungs at times.![]()
