I once knew a man that was campaigning against a proposed metro line because he feared it would be too noisy, harm the environment, scar his neighborhood, etc.

I once knew a man that was campaigning against a proposed metro line because he feared it would be too noisy, harm the environment, scar his neighborhood, etc. One day he organized a walk along the entire proposed path of the new metro line. At the end of the walk, they discussed it and to his own surprise he came to the conclusion that actually it was not that bad after all. His anti-metro group did of course dissolve. I had a lot of respect for him.
