Ilford & Romford are nominally Essex for Post Code purposes and most
people assume they are in Essex

Do they really? Having spent many years living in Brentwood on and off
over the last few decades it (Brentwood) is quite well understood by
people who don't live there as the "First town in Essex" - looking out -
and the "Last town in Essex" - looking in.

The changes to the Oyster fares and introduction of Crossrail is likely
to make more people think Brentwood is in London now.

but in fact they are in London Boroughs
