I had a cracked windshield here in Ohio, (and so did Will). I looked up the laws, and if it's over a certain size, it's illegal. But, if it's under a certain size, it's ok. In SC & FL, I think it was illegal of any size.
Yeah, no hot water, & don't leave your windshield arms up. Many cars, if the windshield arms are up...and they get blown over or knocked over, they WILL break the glass.
