Hello,
My family owns property on Chappy and I spend several weeks a year there. I am against a bike path. 
In looking at the statistics, there are no cases of bike-car related injuries in over twenty years, so it appears that for at least that long both cars and bikers have been able to co-exist on chappy without issue. Since the speed limit is only 25, it is easy in my experience to slow down as needed when driving to ensure for the safety of the bikers, and as a jogger and biker on the island, I have never felt threatened. So I do not feel this is a safety thing. 
It will cost an enormous amount of money to have this installed and I’m not seeing a real need for it. Seems like just a nice to have for some folks.
I can’t figure out the logistics of which side of the road it can be on due to various factors like the lay of the land, water, etc without it crossing over the road at least once or twice which would just end up creating dangerous crossings of bikers and increased confusion.
Most bike paths on the island are in places where there are not many driveway or road crossings but this is not the case for Chappy. The sheer number of driveways would be a safety issue since in my experience the novice bikers that rent bikes to tour Martha’s Vineyard do not understand the rules of the paths and would be less likely to watch where they are going and look for crossing cars from driveways since they are in the safety of a bike path. It is a false sense of security.
Also, a majority of Chappy roads are dirt and it would ruin the feel and charm of Chappy to pave them just to install bike paths.
Please include me in your totals for those against the bike paths.
Thank you,
Kate Oram
