I have visited this scene every few years:
first in August 2005: http://www.pbase.com/pekkal/image/48327563
then, September 2006 http://www.pbase.com/pekkal/image/66603535
a year later in September 2007: http://www.pbase.com/pekkal/image/86047179
and the last time 7½ years later in February 2015: http://www.pbase.com/image/159139821
...
Last +1, on June 3, 2021 (note that the crane has lost its cabin): https://pbase.com/pekkal/image/171689166
Last +2, on May 24: https://pbase.com/pekkal/image/172633710

If there is anything to learn from these photos it is focus: getting the whole crane in photo flattens it, zooming to the hook & cabin works better?
