It is on the news that TV presenter Kirsty Allsopp is being investigated by her local council over child protection concerns over her 15 years old sons Interrail trip in Europe after his GCSE's.
This surprises me as some decades ago when I finished my GCSE's many of my class mates went Interrailling. From a quick google I failed to find any information about who actually goes Interrailling. Is this information available? Is it unusual for people this age to go Interrailling these days?
