Yes Common sense - cover it up and securely too.
Legally the requirement to keep it covered was for younger shooters 14yrs to 17 carrying their gun to a shoot. It was removed by the Antio Social Behaviour Act last year as was their right to carry the guns unsupervised.
Still - cover it up - preferably in something non gun shaped and make sure you have got a good sound legal reason to have it with you.
