There are more similarities than differences...but here are some differences I have noted:
*Canadians walk more; there are no sidewalks in some areas of Columbus Ohio.
*In Maine there are no shoulders on the roads...which is real scary since big lumbering trucks loaded with logs careen around corners, whew! We, Canadians rely on the shoulders of roads for emergency stops!
*Canada, so far, has better health care for all citizens.
*Stuff is cheaper in the States.
*Wages are higher in the States.
*The States have more roadside rest stops for travelers!
There is more, but enough for now!
