I did a cache pretty recently, that had some "false" hints in it... u should have seen the look on my face when it said, don't swim in the pond, think b-4 u act... and that in the center of town with no water for miles around...
It turned out to be a joke, and i have to admit, there was a pond... x-ept it was just a few inches wide... really funny guys...
The cache container made up for the cofusement... what a wonderfull find that was.
I don't mind false hints if they were meant to be funny.... It's not so funny if the area has changed due to renovations and stuff like that, so keep an eye on your cache to make sure those things don't occur. It's always quite a dissapointment.
