In reply to huckleberry:
I believe the traditional ways of footwear disposal are:
A) tie the laces together and lob them over a telephone wire or power line. (This will then cause people to Google the significance of footwear dangling in the area and get worked up by the urban myths suggesting it's a place to buy drugs or the boundary between gang turfs. The local paper will then do an article on the drug dealing gang warfare, with a photo of your dangling boots as evidence of such).
Or
B) chuck them on top of a bus shelter (different bus shelters for each boot obviously ... though putting a pair together on the same bus shelter would be ludicrous, confusing and cause the local paper to do an article on why a pair of boots, rather than the usual single shoe or trainer, has mysteriously appeared on a bus shelter roof).
A copy of the local newspaper would be a more professional and independent record of your boots disposal than just taking your own photo I think?
