Thanks for the great feedback. It's very interesting reading your
comments.

These cards are really aimed at unfortunates like myself and, it
sounds like, Cal, that require a reminder now and then where they're
going. I've already got one of these cards, and I find it very handy.

Have you tried getting close to a tube map at rush hour in a busy tube
station? It's a pain. In some of the quieter stations it's difficult
to even find a map, and the trains sometimes only have maps of the
line your on. And if you've been out partying the network can be even
more confusing.

LT obviously think there's a requirement for handy tube maps as they
give them out free (well, you pay for them via your fare).

A few people have asked me where they can get a credit card sized map,
but you can't get them from LT. Well, you can, but there's too much
info on the LT version and you have to unfold them before use. LT are
aware of my plans and discussions re licensing have taken place.

The maps I'm planning to produce will have the central zones on one
side. The other side is blank at the moment, and suggestions are
welcome. Yes, it is a bit small, but if you can't read it, you
probably should get to an opticians.

I'll keep you posted on my progress, and if you have any more to add
to the discussion please do.
