SInkholes

So sinkholes are a scary thing, they can make your house go from normal to Sarlac pit in no time flat. But where I live is not very susceptible to having a sinkhole. Now one could always happen and we don't have much of a way to tell when a sinkhole is coming, but from what I found on USGS said that  where I live will probably not have a sinkhole ( There is still always a chance thought). Now the bedrock under my house could give out at any moment, but ( and I have no real good way of checking this) from what I know my house is not built on limestone so I think I am safe-ish. And we don't just grab a drill and dig a well or any other man-made reason so I am safe there two. And the final reason I am safe is because i say more than five lines in the entire trilogy.
