That's true, greenery or buildings can cause extra losses. But this 
can be compensated by more TX power. Measurements on 136 kHz have 
shown that additional losses often are in the range of 3 to 6 dB. I 
guess that this will be less on 500 kHz. It just would mean that you 
need 50 Watt instead of 25 Watt.

Shame?
Shouldn't anyone be "free" to operate the mode he (or she) prefers?
Without any mode being superior to another?
And without receiving negative comments (such as naming QRS "Lazy Mans cw.")?

To avoid misunderstanding: my HF logbook is filled for about 50% with 
CW QSO's, for sure I am not anti-CW. But nut anti any other mode either.
