You might be a sinkhole if...

The appearance of a hole in a Middleburg yard had the home's resident concerned, but when more started appearing and growing--and in light of the Tampa-area sinkhole that claimed the life of man who lay in his bed--this Middleburg  woman's concern started growing too. First Coast News Reporter Sade Malloy sought out the expertise of  FSCJ Professor Rob Martin, Ph.D. , wearing his geologist hat, to learn a little more about the nature of sinkholes. (NOTE: Dr. Martin does not rule out that what the resident is witnessing in her yard could be a sinkhole, although the linear arrangement is less characteristic of those phenomena than a more circular depression or hole.)
