Fair play, this time you are eschewing flying but you did fly the last time while all the time exhorting others to reduce their driving when much of it is absolutely essential. This time you are driving (and unless your electricity for that is renewably generated) there is still a CO2 component to that. Relative to car use for the daily necessities (getting to and from paid employment, doctor's appointments, shopping, etc, etc) how do you justify your trip with your assertions that everyone should drive less?
