Hi all,
I'm going to a gig at the Camden Roundhouse tomorrow evening and,
ideally, would like to park somewhere further up the Edgware branch of
the Northern Line. Somewhere around Hendon Central would be good, as
I'll be coming down the A1.

I've checked on the TfL website and the car parks aren't big (or are
non-existent) for that area. I know you can park (for free!) at Brent
Cross shopping centre, but I don't know whether I can stay there until
11pm or so.

Does anyone have any other suggestions for that area?

Thanks,
Sam
