Question mark?

Day 4 of our Cornish holiday took us to Newquay, where these shells caught my eye, looking as they do a bit like a question mark.

Newquay is a lovely area but a dangerous one too, as Sunday's tragedy demonstrates only too clearly.

Thank you so much for all the comments on my 1500th Blip yesterday. I will reply individually but it's unlikely to be before the weekend. Life should (hopefully) calm down a bit at the end of the month.
