Those of us with very good antennas for 80 and 40M, and especially those 
with directional RX (either a beam or Beverage) are well aware of long 
path openings at certain times of the day. Last winter, while CQing on 
80M, I made a half dozen Qs to Ukraine split between two mornings. Post 
contest analysis showed them to all to be within about 200 miles of each 
other, and along the grey line. At other times, I've made long path 
openings to EU in the morning.

While operating from Chicago with dipoles for 20-10, there were periods 
of an hour or two during DX contests when I was hearing EU stations 
equally strong via short and long paths, to the extent that they were 
completely uncopyable.
