Escape Hatches

In conversations, some people mentioned shorter versions; either by design or as a back-out plan. Here's a summary of what has been mentioned or found out:

1. 1 person who lives in Brighton is thinking of meeting us in Newhaven
2. 65 miles into the French side we ride along a suburban commuter train line. It runs from Gisor to Paris St Lazare stopping about 20 times. It takes about 1.5-2 hours, costs about €12 and runs about every 90 minutes. The timetable (so I don't lose it) is here: https://docs.google.com/viewer?url=http://www.paris-gisors.com/docs/Horaires_Paris-Gisors_Samedi_Dimanche_Fetes.pdf
3. We should have car backup too.
