At least you could get a bus to and from Banbury town centre.
Moor in Cropredy [long term, visitor or marina] and you get 2 buses a week, Thursday and Saturday. Despite requests for Stagecoach to route their Daventry - Banbury service through the village [s they had to a few years ago when the flood relief works on the '361 closed the road for months], they refused. That would be an hourly service. That bus runs from a different depot not connected to Stagecoach in Banbury and I believe it is county council concessionary funding that's getting in the way. No-one outside of a metropolis can rely on any form of public transport, 24/7 or otherwise.
