Continuing on.  There's a wiki page that gives a list of the more popular sinkholes around the world,  these are the more prominent ones listed for Florida:

• Devil's Millhopper – Gainesville, Florida. 120 ft (37 m) deep, 500 ft (150 m) wide. Twelve springs, some more visible than others, feed a pond at the bottom.
• Winter Park Sinkhole, in central Florida, appeared May 8, 1981. It was approximately 350 feet (107 m) wide and 75 feet (23 m) deep. It was notable as one of the largest recent sinkholes to form in the United States. It is now known as Lake Rose.
• Kingsley Lake – Florida. 8.1 km² (2,000 acres) in area, 27 m (89 ft) deep and almost perfectly round.

The name of the first one is an addition to the recent "Devil Theme" pattern-cluster... which jives somewhat with the recent "Hog Theme" pattern-cluster... and speaking of which, two films listed on the Netflix "trending" section fit, and of course I've watched both:

• Horns
• Mr. Pig

From the wiki pages of Mr. Pig cast/crew:

• Douglas Crise ( born May 1, 1961)
• Diego Luna Alexander ( born 29 December 1979) 
• William James Remar (born December 31, 1953)
• Danny Lebern Glover (born July 22, 1946)
• Maya Khabira Rudolph^[1] (born July 27, 1972) 
• José María Yazpik (born November 13, 1970)
• Joel Murray (born April 17, 1963)
• Angélica Aragón (July 11, 1953) 
• Alejandro Luna (born 1 December 1939)

Release dates	January 26, 2016(Sundance Film Festival) July 22, 2016 (Mexico)

Re of those mentioned on Horns wiki page the following stand out::

• Alexandre Aja (born 7 August 1977)  
• Daniel Jacob Radcliffe (born 23 July 1989)
• Juno Temple (born 21 July 1989)
• William James Remar (born December 31, 1953)
• Sabrina Ann Lynn Carpenter^[1] (born May 11, 1999^[2])
• Michael David Adamthwaite (born September 1, 1981)
• David Bowditch Morse (born October 11, 1953) 
• Shia Saide LaBeouf ( born June 11, 1986)

Between the two films two clusters have expanded:

• December 14(x3),_, _, _, 18(x3), 19, _, 21, _, _, _, 25, _, _, 28, 29, _, 31(x2)/Date Sequence" pattern cluster
• "June 7, _, _, _, 11(x2), 12, 13, 14(x2), 15/ Date Sequence" pattern cluster. 

Going back through todays posts I find three others that form clusters with the above:

• Leopold Stokowski (18 April 1882 – 13 September 1977)
• Thor Heyerdahl (October 6, 1914 – April 18, 2002) 
• Harry F. Olson (December 28, 1901 – April 1, 1982) 

And April 18 is the 108th day of the year-- an important number according to Yoga buff butt MacGregor.
