In a way, I don't blame them for coming out at night. It was a scorcher during the day. Nearly 100 degrees. And it wasn't a dry heat.
It appears that there is a problem with pranksters or vandals with geocaches in this area. This, however, was the first one I encountered where the container wasn't stolen outright. Not sure what's with the moving and hiding a different way but several other cachers have noticed a lot more of this happening.
