I did almost everything from St. Nazaire northwards including the two wonderful Tumuli and a dolmen at Pornic and loads of menhirs as well as some other pretty dolmens.
I also hit a load of stuff near Le Bernard in the south Vendee which was pretty blowing, icluding a rather displaced Angevin temple dolmen (usually found between Anger ands Saumur).
I'm back in Carnac and have so far clocked about 230 photos since February of sites in NW France and Brittany.
Need to get up Barnenez on the north coast before the summers out, as well as the magical forest of Broceliande and a return to trip to the Isle aux Moines in the Gulf of Morbihan. I have no idea if I'll have the time...
