Terry, 
For what it is worth, as an avid bicyclist as I know Dr. Adibi is, I agree with him and have serious reservations as to whether bike path on Chappy is advisable. I think the residents should be better informed and, after information is distributed, the issue should be fully debated by CIA before any advocacy position is asserted. 
FYI, I am a member of Transportations Alternatives in NYC, commute in NYC by bike, and have been pushing the creation of bike paths in NYC. However, I believe that the Chappy ferry is a unique natural regulator of auto traffic decreasing the risk of bike accidents on Chappy. I believe we should consider the negatives as to the impact of a bike path on the rural charm of the island and whether any objective evidence exists that a bike path on Chappy, in particular, would significantly enhance the safety of bikers. If a bike path is being seriously considered, I believe the residents of Chappy should see it in its proposed concrete form, ie a map or model, so we can objectively weigh the real impact. If government funds may dictate the creation of a 12’ wide bike path that will substantially impact the charm of Chappy roads and invite moped and other illegal use, I not sure the upside on safety will be significant. FYI, my doctor of 20 years recently was killed when a truck turned into him on the NYC Westside bike path. I could see a similar problem with cars turning into the hidden drives on Chappy, particularly at night. 
I know there is a dedicated group on Chappy that have been fighting for a bike path for years, and I was initially a supporter of the idea in the abstract. I respect their intentions and am mindful that these concerns may present just one more delay. However, I believe, once again, the rural beauty of Chappy is just too fragile to approach it any other way. 
In the interest of full disclosure, since our house is near the main road, I am also concerned about the impact of 12’ paved bike path adjacent to our house. Before taking a final position, I would like to see the real size and proposed route[s] of the path. 
On the pro bike path side of the debate, I can see an argument in favor of safety of children on bikes, but again, am not sure the Chappy specific evidence, if any, necessarily will support a path even for children. The best safety for bikers is often to just increase their numbers on the roads. Adding more asphalt to Chappy, whether road widening or a hidden bike path, may just increase the speed of both bikers and autos. 
A question to think about, are all those advocating a bike path the people regularly on bikes, like Dr. Adibi, or the people in autos who would rather not be inconvenienced by the bikers? 
You may share my thoughts if you like with the membership and/or the bike path committee. 
Thanks again for all your excellent work.
