I am loving the weather, but am not a big fan of the tube in this weather. It is normally super horrible, but the new circle line trains with aircon are my new favorite thing.
In fact they are so good if the next one is only a minute away I have started waiting the extra time for them.
I do worry what happens if the air con breaks down on them….. so far this has not been a problem I have noticed, but the lack of opening windows could be intreasting. Then again it is a good thing whilst everything is working.
