Sorry this is completely off topic, and if anyone want's to report it as inappropriate I will understand.
I read this on a Lanzarote based FB page and thought it worth sharing, as there will be many people either already on holiday, or going soon, that may be willing to keep their eyes open.
"Missing British Woman.
Her name is Margaret Holt. She is aged 65 but looks younger. She is of slim build and has light mouse brown hair. Margaret was wearing a pink vest T shirt, khaki shorts, walking shoes and a small black ruck sack. Margaret loved walking and hiking. She may have gotten on a bus - nobody knows. She may have fallen.
If there are any walkers out there please can you keep a close eye out for Margaret as she may have fallen and not be able to get help. If anyone saw or met her walking please can you contact the Guardia Civil as they need to get an idea of where to concentrate their search.
Can you please tell as many people as possible as the Guardia Civil need all the help they can get."
