Not particularly. However, when I was working one of my shifts meant a 2am ride home for a week every month. Owls, deer, badgers, ravers, doggers and cottagers (was once offered a hand job by a cross dressing bloke, which I politely declined), thieves, loonies, and just occasionally other cyclists too.
They o ly come out at night, except here in Northamptonshire where they often come out in the daytime as well.
