The possible locations for Kim Remmel are pretty far from Rye- not an impossibility, but if her vehicle is also missing it seems unlikely someone would not have spotted that in the area. It's a small community, the kind where there are tourists that come and go but locals all know each other.
It's interesting to me that the first reports say remote area, and then the location pin is not. Rye is small, yes, but the pin appears to have been dropped just in the center of town. I was envisioning somewhere in the mountains, which that is decidedly not.
(My boyfriend's family owns land in Rye and we go there frequently; if remains were found at that pin they would have either had to have been concealed in a man made structure, or placed there very recently. Those areas are mowed frequently.)
