Your neighbors are brave, I ran my coil on Halloween night
downtown at my cousins house, I only had three people ask me anything
about it the whole night, running it in public for about 4 hours (on
and off of course, short 1-minute runs as people walked by on the
safety of the sidewalk) in front of just about every person who passed
by. I guess the people of Berwick Pa don't care about 5 foot
