Not mine or caused by me but I've seen two spots with two different types of horse manure in two close together areas while traversing on foot in P Penarth.
The heavy straw load is in the small lane going to the Ash Path from St Davids Crescent estate and the other (see all pics with the map location) is halfway up Sully Rd near St Joseph's School on the pavement.
Available to anyone needing free manure just go and collect as it's free to anyone in public! Just thought I'd point it out so it's not wasted.
