Snot-rocketing? Is that frowned upon?

In general almost everyone is a good person with some quirks (unless you interpet threat levels from the news). Are avid cyclists a slightly higher percentage? Probably no more then avid anyone's, The same for avid RC plane flyers, people with different education, income, family history, and any other number of social/economical factors. That being said, I don't trust or not trust anyone differently at face value regardless of any of the above. I will leave my phone or laptop out on an Amtrak train or a plane and walk away but I'd never do that on the subway or a mall food court.
