In reply to Tru:
I was supposed to be going to Font this week, but cancelled at the last minute on account of the weather. Hoping it will improve over the next couple of weeks and will be able to go then instead. The long range forecast for the end of the week after Easter is looking a bit better, but not sure about its reliability.
Nearest sport climbing to Font is between Auxerre and Dijon(over 100k south of Font, but quite quick to get there on the A6). There's a small indoor wall (Bloc'age) at Arbonne la Foret, and several larger ones in Paris.
Was tempted to try Albarracin in Spain for a change this year, but quite a bit more expensive than hopping over to Font.
