A visit to the huge storm drain/culvert in Derby's Markeaton park. Perfect weather to go exploring underground as there's not much water. I did't go right to the end as its the same looking tunnel all the way.
@@RebeccaFyre where does this one come out? i am trying to track them all on Google maps. theres another one in Darly abbey that my grandad went up in in a boat when he was a kid. after a while though he said it goes up hill!
