Small and peaceful place, but I really liked it.
Nature is beautiful !! There are several beaches on the ocean, but I swim more like lakes (warmer and calmer water, no wind) which normally has at every step.
The relief is mainly corrugated character, but with no major hills / mountains. So it's little real trouble, riding a bike, but nothing terrible.
One can find another job without any problems, but if you want a high hourly rate, then it is not so easy, but possible!
As for transport, I have only used the bike and I was not exactly easy because we all have jobs and accommodation away from each other. So it 3-4 times a day 20 minutes purchases at least an hour. Forget the bus to work, except perhaps to the nearby where you can bike.
http://www.chathamhoodbikes.com/ - if you can not find your way from some of the bike, it can be purchased for ~ 125 $ (but mostly older bikes)
http://www.capecodtransit.org/h2o-route.htm - a little tug with that bus will because it is quite slow (you can stop anywhere outside the station, as well as for output)
All in all, the scooter would be the best solution, and only with the car you have a huge advantage.
Eh, accommodation can be a problem. Difficult it is, but I do not know anyone that came without advance secured. I have no concrete information to give you where to turn, I'm all known ad: http://capecod.craigslist.org/search/roo
In addition, employers should ask just in case.
The sooner you start to look better!
Price averaged $ 125 / week.
