Canal to Keadby, over the Trent to Gunness, Flixboro, Bagmoor and bridleway to Roxby, over the Ancholme at Horkstow, up the hill and right along Middlegate then left under A15 to Kirmington, cross A18 and up the side of the airport. Left to Gt Limber and follow road to Swallow then left to Hatfield, left again to cross A18 to Waltham then it’s just a wiggle into Cleethorpes from there.
Ernie Becketts in the marketplace is the chippy you want.
