For those of you planning a UK trip in the near future, you
may find the following URL useful.
http://www.multimap.com is a beta test version of every
house, street and rabbit hole in the country. Seemingly
mapped in detail over the last 6 months.
For those of you planning a trip to Gaydon too, there's an
entirely new website (believed to still be at beta test
level) at http://www.heritage.org.uk Before there are
complaints, I had NOTHING to do with its development and
there's LOTS more to go on it - including interactive pages
and on-line ordering of goodies from the Centre's Shop.
