My guilty secrets

I've just used something like 500 kg of CO2 as a passenger on an aeroplane to Athens and back. Oops.
Just back from a trip that combined professional work and a holiday, in Greece. The travel was organised by a travel agent in Greece. You sort of think that when the place is four hours away by air, you need to fly because the train travel would be too long and complicated. But I think that's not really true. We were put to shame by one of the participants on the course we were teaching on (a summer school for classics teachers) who had travelled out by train.
Well, at least we managed the work and the holiday on just one set of return flights. But still, none would be better than one.
Now I've discovered the most wonderful web site which tells you how to get to anywhere without using a flight, and how to book trains and ferries instead. It's at The man in seat 61 (I'll add the link to my list of links on this blog).
Perhaps I should think again about my trip to Toronto in the autumn?
