I'm Paul, the organizer of Tokyo Rubyist Meetup. We'd love to have you
participate in the meetup tonight. Unfortunately, I can't meet you at
the airport, but if you can make it to the nearest train station, I
can pick you up from there. The venue itself is pretty much on route
from Narita to Haneda airport:

If you are interested you can give me a call at +81-90-1880-8528
(090-1880-8528 if dialing locally), and we can work out the best way
for you to get there.
Paul
