Studded tyres are only legal in the UK when there is sufficient ice or snow not to damage the road surface - so you would have to keep a set of stud tyre wheels at home and change them if it snowed - but if you drive on a road which had been cleared they become illegal again.
Same is true of chains.
I can't imagine there are too many places in the UK where chains would be useful.

Actually they are galumphing great idiots and soft as they come .

Jemma, I, and many others on the forum use an Arctic Butterfly brush.

If you go the Eclipse route make sure you get the right fluid for your sensor.

Alternatively Pentax have a sensor cleaning kit.

I'd suggest starting with the Arctic Butterfly and only go the wet route if that doesn't shift everything.

A full battery is essential. The first time is nerve racking but it is easy to do.

Looks good, but will some Glaswegian jobsworth come along and tell us we can't take photos on council property?

Edit: Actually the heavy horses are of interest. My daughter-in-law's mother rides a Clydesdale. DIL rides a Shire

Forgot the podenco canario - a greyhound type of dog too - but capable of jumping over 6 ft fences as if they don't exist .

They come only from La Palma - Perro de Pastor Garafiano, aka Garafiano.

There is also the Bardino, which come from a couple of the islands, including Tenerife, and of course the Dogo-Canario which is a different kettle of fish entirely.

Have a look at www. garafiano.com for information about the breed.

You need to fly from Manchester for La Palma I believe.
It ain't as cheap as the other islands though. But then it's not as crowded, and a lot greener too. If ever you do go try and stay on the west side of the island.

We've practically given up on Cuba for winter sun and will probably go back to La Palma again. Either that or we'll go in June for a big festival there with lots of dogs of the same breed as one of ours. A lot depends on whether my husband's contract gets renewed or not at the end of the year.

If I spoke better Spanish I could happily retire to La Palma .

Gran Canaria has some lovely scenery once you get away from the tourist belt.

But I am sure you will enjoy Tenerife - it has to be better than Worcester in November no matter what .

There's lot of info on Tenerife on the web btw .

Looking at the Silkypix site it says there are some limitations do developing the DNG format. It says to refer to the "DNG Correspondence" section of the manual.

Interesting that it supports 645D RAW already, but not K-5 or K-r.

Do let us know how you get on Jonathan.

Sorry I can't help with walks and things - I've never been further than the airport in Tenerife.

I've photographed Teide though, from La Palma.

If you can get a boat trip do so - you should see pilot whales, and dolphins and if you are really lucky a sea turtle, barracuda or similar.
Some boats have a glass bottom which is just great for viewing the beasties.

Be prepared for some rain - November is rainy season. But it is mostly only rainy at night.

Have fun.
