Help with slasher/woods/campers movie name.
I saw this horror movie around the late 70's or early 80's at the drive-in.I think there are a few campers deep in the woods that get killed one by one. One person running away runs right into some sort of sharp trap. Strings or can lids, that are tied to trees springs up and cuts him or her to pieces. At the end of the movie the one guy who is left running from whoever comes up on a logging site or railroad tracks, ( I wish that I could remember the details better) I think somehow he escaped. Any ideas? Thanksshare
