Advice on using the London Underground this summer.

I would add, carry a bottle of water at all times, and remember that it can be very hot indeed in the deep tube stations at busy times (not unusual for temperatures to reach the thirties in summer at peak times).

This is a test of the WiFi ability of the Oxford Tube. I'm returning after a really frustrating trip to the BL (a wasted one, really), but on the other hand, an excellent afternoon and evening visiting the Hogarth exhibition and then seeing Chicago, which is in the (salty) popcorn category intellectually, but has some good music and, in this production, some very impressive dance numbers, even if the costumes did seem aimed squarely at the male section of the audience....

Oh, and the WiFi works well, but I think typing is making me sick, so I'll stop.
