The best one i ever did , apart from the odd mouse now and then , was when i lived in London .
It must have been when i was about 15 or so , so about 40 years ago , when i used to go and watch the boat race .
This particular time i went and was doing my usual explore thing as i wandered along the bank of the Thames , when i came upon a roped off area , with a sign saying 'keep out' , which to me reads ' i have got to see what's in there ! ' , anyway , under the rope i go , down the muddy slope , had a look around , a few tarps here and there , some wheelbarrows etc . So not much of interest "just a building site" i thought . So i went to the other side of this 15' deep pit i was in to climb out . I got half way up and slid down onto a pile of sticks ? Only they weren't sticks , they were bones ! Human bones , legs , arms , skulls the lot . Not just one or two , but thousands of them .
I got out of there pretty quick .
Turns out i had gone into an excavated plague pit of the 14th-16th century .
It seems they used old dry docks to dump the plague victims in at some time .
They find new ones every now and then when new building work starts .
So if you see a sign saying 'keep out' it may be best if you do !
Ring a ring of roses ! lol .
