Its true, not something unfamiliar in the geocaching world to have stuff like this, minus the £30 and condom though!
The note said (I don't have the note but its near enough):
Then it had an address under this...which was about 500 yards away, it looked like a secluded house next to some water.
I mean WTF....I was like shattered from walking at this point and there was no chance I would go to the house alone, no idea what would be waiting there for me..
Went to get the next train back to Leeds and its safe to say I didn't bother telling the wife about it, too many questions to answer
Had some weird shit like this happen to me in my past, sadly no real exciting ending. Not really thought about what was on the video, but it still might be there.
