Bob, I expect you're an excellent planner. But you know what they say about
the "best laid plans of mice and men...."
Make sure you take the information on pilot charts with a small grain of
salt. Remember that the information is derived from ships that report the
real weather during their transits. Ships do divert to avoid bad weather,
the incidence of bad weather reports is skewed on pilot charts. Bad weather
occurs more often than the charts indicate.
Nobody can plan for overcast weather. Sometimes, those systems just hang on
for days. If you can't see the sun or the stars, you can't get a celestial
fix.
Then there are the really clear days when you can shoot Venus in the
daytime! That's a rush...!
