Answer:
I am a path between high natural masses; remove the first letter to get a path between man-made masses.
I'm not really more than holes tied to more holes; I'm strong as good steel, though not as stiff as a pole.
I am a fruit with seed on the outside.
I always murmur but never talk. Always run but never walk. I have a bed but never sleep, have a mouth but never speak. What am I?
I like to twirl my body but keep my head up high. After I go in everything becomes tight
The warmer I am the fresher I am.
