I have also spend much time getting lost in the golf cart when I have rented in TV. Most people are very willing to help the lost lambs find their way...
I rented in Chatham for one week last year, and I don't know if Chatham is close to the train tracks, but I never heard the train once in 7 days last year.
Good luck to you, and I hope you are soon a resident of Calumet Grove!
