Chris gurgled happily, sounding much like
they were saying:

It depends a bit on the time of day, but I'd suggest Rickmansworth
offpeak and Chorleywood peak. In both cases you can exit at j18 and
join again at j17.

Completely agree with Roland - we do it regularly,. Denham is harder to
get to, both for pickee and picker.

C'wood & Ricky are tube fares, too - much cheaper.
