My son was born at that hospital 13 years ago next week. It was an active tornado alert season there that year too, and they've had several tornadoes touch down in the town over the years, but luckily one never touched down while I was there. But, I always hit the deck when those sirens went off. This Utah girl was FREAKED out every time. The neighbors would grab a 6 pack and a lawn chair and watch the storms roll by, but I was ducking and covering in the nearest basement.
The hospital that got wiped out was St. John's and luckily they've got another hospital, Freeman Hospital, right around the corner amidst all the devastation as well, that is still ok.
Horrible tragedy...glad I don't live there anymore, but wish I could be there to help out.
