Not if the shut off valve is located at the far end of the crawl space and access is through a hatch in the floor of a closet with about a zillion things piled on it, like at my house. I've never turned the inside house valve off, always used the valve at the street. Besides it only requires a Crescent wrench. Now if I needed a special wrench, I would paint the handle RED and would hang it by the garage door and always replace it whenever I used it. Course that would keep some idiot child or spouse from moving it, but if I had an idiot child or idiot spouse (or an idiot me) I would buy a second wrench and hide it in a special place that I would not likely forget.
What I can't imagine is having a flood from a broken pipe or valve and waiting for the water company to come turn the water off.
