Good point re: the views of communication.

Good point. Many have been so despoiled, but not all, and that's all I have to say
about that, lest my favorite unspoiled places become the next popular place to
trample. I should note that the difference between tourism and the type of
population distribution I'm talking about is that it may not despoil so much as
make the beautiful inaccessible due to the privization of right-of-ways, the
development of former camp grounds, etc.
