Key to driving 209. Be respectful, slow down in key areas, don't do more then 5 over. There are actually 2 or 3 phippsburg officers and you never know where they will be or when they are on duty, probably will be "on duty" if a complaint is made. I would only worry about Bath PD bugging you getting to 209. Only way to get away with speeding is being in a obvious work vehicle like a 1ton dump truck.
The drive down to Popham would be nice and we could even go other places. If this is something you want I can always go scout.
