The CNEF has another training day on 5 November, directly about Church Planting.
This time it's a bit further out in Paris in the 19th Arrondissement.
I just priced up going: we're talking roughly:
60 euros return on the cheap trains
60 euros to stay overnight (cheap hotel or AirBnB)
20 euros fee for the day
40 euros for meals, say - one whole day and an evening
About 180 euros for a training day.
I could save by travelling up overnight by coach, but it does seem to make you sleep during the sessions, and I have to preach on 6 November.
It would need to be extra-specially good to merit that cost, so I'll give this one a miss.
