Yes bruno i totally agree things should be locked up,but our allotments are out the way,theres no electric so growling dog noises and security lights are out the window.
I did have all my loft locked up with big padlocks etc and what did they do,just simply kick the doors of there hinges,not forgetting lofts are mostly made from ply wood which is not that hard to break.All that was taken was my tools drills etc and caused a lot of damage.Once this happened they saw my loft as an easy target and this happened 2 weeks in a row,thats when i rescued an american buldog (charlie)and placed him at the lofts,my dog is just smaller than a bull mastiff and bigger than a boxer dog,and very loud.
no hassle since
