From Wim's travel report:
MRM is located in the northeast of Marseille.
According to the GPS, I am approaching a dead end road, but where is the beacon?
The road is on top of a ridge, and suddenly I see MRM on an adjacent hill.
A lap around that hill takes 45 minutes, and then I'm back at the same point.
Get out of the car and see if there is an option on foot.
Yes, there is, but MM is another special model built low to the ground.
I walk past it for a while and luckily find an opportunity to take photos.
How, I already described that a bit last year! (TIS, August 9, 2010.)
