We have written before about catching the bus to Tours. This is an amazingly simple and cheap way to travel: the just under two hour long trip costs €1.70, and the bus leaves Preuilly at 7.00am, 10.10am and a couple of times in the afternoon that don't affect us (full timetable here).
One improvement in the bus we noticed this time is the new laser display screen (actually, digital display, but I'm sorry, I haven't a clue about these things) which gives all sorts of information for travellers.
you where it is going
At least - that's what Susan and I agreed we usually do.
