Personally the once a year I get the urge to eat a Maccy D - I won't be throwing it out the window. Always regret eating it but can't help myself.No i am the sought of person that tells people to pick their crap up!
But plastic wads on a clay ground is hardly chucking your half finished maccy d out the window of the car!
I am at a loss as to why game shots with their love and respect for the countryside would use anything but fibre?
