Let me ask a stupid question. First I have read the thread to date.

If your vehicle won't be able to fly out of ground effect (and you
don't plan on flying over water) where will you fly it??? I don't
think ground effect goes up and over obstructions (houses, trees,
water towers. electrical power lines, etc).

We've got these large skinny areas of flat surface connecting major
metropolitan areas.
