From Friday 6th (my last day off)
I was out, just pottering about
One of the places I visited was the old sand quarries (Horbury Lagoons) just north of jct 39/M1
The last time I was down there, it was a fishermans access, with gravel roads, & a consistently flooded bridge under the railway
Further along, there was some fairly decent (& I've been told, actually Council commissioned) graffiti art on the tunnel under the M1
This one must have been painted over, or I'm pretty certain I'd have noticed it, unless my attention was fully taken by the two below (+ location map below photo)
