I did work it it out a few years ago and it was quite staggering and that did not include diesel ,one permission cost me about £25 in diesel each time i go
Still cheaper shooting than going to watch England play football , that used to cost me at least £1000 every away game , about four times a year and £300 for a home game at Wembley and even more when we had to go to Manchester . At least £5k a year and nothing to show for it ,apart from disappointment , I could of bought a daystate and got the same feeling
