I'll give you a concrete example: In 1936 or 7 my father bought some
forested acreage outside our home town with the idea of cutting some
of the timber to finance the building of a house. Along came the Great
New England Hurricane, in 1938, and blew all the trees down and as
blown down forests were all over New England the timber became nearly
worthless... so a very small house :-)
Now, this hurricane was the first major hurricane to strike the area
since 1869 and is most powerful, costliest and deadliest hurricane in
New England history.
What do you call this?
Sounds like he put all his eggs in one basket. To bad he " bet the
farm" on one roll of the dice. What was his plan B in case the ****
hit the fan...... as it did in his case?
Another chapter could have been, a fire burnt it all down and the
price of timber went sky high but there was no marketable timber left.
There are several possible takes on that one.
Personally, my relitives left Houlton Maine in the late 1850s and
headed to the Oregon Territory to log and then farm the land. They
seemed to do just fine... humm maybe the PNW was a better deal than
Maine

Its all about knowledge and judgment. Observe, predict, take
corrective actions. Learn..... and the world becomes simple.
Ya ever wonder why some people always have all the bad luck... you
know like driving a perfictly good boat on a reer, constant motor
problmes, and a never ending list of system hassels Oh and people
problems?
