I see you're stating this from Florida. West is down the road from me but you know best. Can't you even bother doing a little research? As has been reported many times, the fertilizer place was built in the country long before the town grew out toward it. The school and nursing home were built afterward. Look at a map and you'll see for yourself.
How much friggen research is required? The explosion destroyed houses, apartments, a retirement home, some schools and more.
Get over yourself. Only idiots would have allowed this situation to exist.
