I know it's summer in BC, but isn't that mosquito time? how cold do the nights get?.. I lived in Toronto for some years, and Montreal, and sometimes that was like Rangoon in the summer, but my experience of the west coast is totally of winter months..
By my reckoning, there are two vans, one with two bodies in it, one with one body in it, that doesn't belong to the van, ( so where did that body come from ? and how did it get there? ) and two missing people without a van. Unless they have the van (?) or car of the lone dead body . Have I got this right?
