Metal detectors on the Tube for Notting Hill Carnival

Going to Notting Hill Carnival?

I heard on the radio earlier today that there are going to be "airport style" metal detectors on the London Underground this weekend to try to crack down on the expected crime levels at the Notting Hill Carnival.

So I imagine that this will make the Tube even more congested than normal. Nipping over to TfL's website to try to find out more about this, I was faced with the powers that be in publicity struggling with the quandrary of what to say about the carnival.

"You'll have a fun time with friends", but "Don't meet them outside a Tube station"

"The easiest way to travel there & back is by bus or Tube" v "Walking is sometimes quicker and easier"

"You'll have a brilliant time" but "Think about your return journey before you even get there".

Overall the message seemed to be:

"It's great, go there" v "Don't use the Tube".

I haven't been to the Notting Hill Carnival for years, but when I last went, like thousands of other people, I used the Tube. Even though I live in West London I never considered that "walking is sometimes quicker and easier". To me it was part of the fun to get on to a fit to bursting Hammermsith & City Line train & walk from Westbourne Park.

Any tips on "quicker & easier" routes? Oh and remember, if you go and see the metal detectors, try not to comment on their effectiveness as you might find yourself hauled over by the police.
