I'm new to all this and am yet to go on a hunt but plan to on this coming weekend.
Funnily enough I was thinking about hiding a cache at a cemetery where I have family and even to a point where I was considering a hide near my brothers grave (Many years ago at 16) anyway I thought it would be nice to have hunters come to his grave and maybe say hello whilst there
I actually thought it would be a nice gesture and I'm sure he wouldn't have begrudged it.
Still I rethought it and figured there may be some unspoken rule re this one and left it to give it more thought later . I still may go ahead with it and use his name in part of the clue somehow.
Either way I agree with the side of do it, but keep it respectful.
