guns
If you were about to try driving from London to Manchester and aware of a high risk of murderous attack by the infected, would you just take the odd baseball bat and machete? Wouldn't you rather take a few guns and plenty of ammunition too? I'm thinking it should be possible to pick such items up from unattended gun stores, police stations or army barracks. Or is it that we should supppose they've all been looted already?
