Here be dragons

Whistler had an email from an FoW:-

Hi Whistler

Have a look at the following

www.streetsensation.co.uk/markets.htm

You may notice something missing.

The area shown doesn't extend to Greenwich, but you'd think there'd be a mention. This is supposed to be a map of markets that are all within easy reach of Central London. According to TfL, it takes between 37 and 50 minutes to get from Charing Cross to Shepherds Bush Market (which is shown), but only between 23 to 28 minutes to get to Greenwich Market. Ho hum.
