A Ferrari factory tour and the Tazio Nuvolari Museum in Mantua seem romantic enough destinations to me but one of our friends last night suggested a nature ramble might be a more appropriate honeymoon activity. So after breakfast this morning we set off to the BaumWipfelPfad or "Treetop Walk" at Saarschleife. We had a short, pleasant walk from the visitor centre on a high level wooden walkway in the canopy of a forest to a spiral overlook structure above the banks of the River Saar at a point where it makes a horseshoe-shaped meander. It was "wunderschön”

The photograph of the viewing platform will give you some idea of the amount of serious engineering Germans are prepared to put into improving their view of a beauty spot!

One of our friends, now a naturalised Luxembourgoise, was born in Strasbourg. On her advice we abandoned our previous plan to visit the European Parliament building in her home city. Instead she recommended a restaurant where they specialise in a healthy, fish-based version of the usual, meaty Choucroute Strasbourgoise. So we headed off through Germany (where we got Speranza up to 225kph on a short stretch of unrestricted autobahn) and then France to sample that. It was excellent.

We then walked around the outside of the amazing Gothic cathedral in the blistering heat (32 degrees C) before heading back to the car and driving to Lucerne.

It was a great drive, though mostly through France so lacking in high speed opportunities. We found our way through the pedestrianised old town (as advised by the hotel and assisted by a police woman who gave us directions) under the disapproving gaze of hundreds of passing Swiss. It's a beautiful country but the locals love their rules so much that I never quite feel comfortable around them. I always feel they are looking for an opportunity to call the police!

After unloading our bags in the narrow alley outside the hotel, I left Mrs P2 to check us in and arrange for the luggage to be taken to our room, while I drove Speranza away to a modern car park across the river where vehicles are allowed.

On my return we took a short walk around Lucerne, photographed the famous bridge and forewent dinner to have ice cream instead. This cooled me down to my optimum operating temperature and was a rare treat under my new dietary regime.

Tomorrow we head for Mantua and the museum of my hero Nuvolari, the great racing driver.
