Who is this family, taking their children up Snowdon via the Llanberis path in unsuitable clothing and footwear?

I'll tell you, it's a photo of my mum and us four children and we're dressed in our everyday windcheaters and Clarke's sandals, but we probably had a pair of mum's tights on underneath our trousers!

I've been trawling through my Flickr account and enjoying the memories. I only know the year of these shots, not the month or day, so you get random.
