i see this to a lot of people have posted on this topic about smoking the drugs, if you want to waste your health and your money go ahead but if you have a sliver of common sense, you will hand them in to the authorities.
my worst cache is one where the clues on the sheet weren't clear and i had to ask 3 or 4 other members for help.
i have been back 3 times now still haven't got it.
i have also found a "vandalised" cache lying 100 metres from where it should have been.
only found it because a friend was looking for a good stick to put his name on.
