I've had a lot of those same reactions. When I'm on the road (on my bike) there is always someone who comes up to me and tells me that they used to have one or knew someone who did, etc. But right after I got the thing there were a lot of "those things are dangerous" coming from people that just don't know what else to say. That's why a lot of those people seem indifferent in their reaction... they just don't know much about them and don't know what else to say. It is unfortunately that no one else here at my work shares my hobby, but there are a few that have become interested in the past year or so, so who knows.
