No, it is an office to create tourism in the region. Nantes is the 4th or 5th largest city in france, hmm, maybe 6th or 7th, I'm not keeping score, I never go there unless for some strange reason I need to. About 20 minutes from my house.
I can get free tickets for the elephant, the other machines, certain museums, etc
The cruise on the river, my wife swears we never did that, but I remember very well it was too fucking hot on the boat and the windows didn't open, she pointed out a pink lighthouse that is now converted to a small luxurious tiny BNB with 2 rooms.
Been years she says we never did that, been years I say then how the hell do I know about the BNB?
