All I know is what I've read in the msm. I don't do FB if at all possible because I find it upsets me.
Oh, plus what I know from a lifetime of living in Iowa. I had never realised so clearly before that Iowa has soaked into me bone deep.
My guess, based on something Heather said in her first interview after the girls were found (without her husband), is that the girls' bodies were skeletonized. There was some sort of reference to the fact that when the time comes to bury Elizabeth, they will be burying bones.
So my guess is that the girls' bodies have been at 7 Bridges park since 13 July.
One thing I do know, to try to shed some light on the scene. Seven Bridges has been described as a "popular" hunting and fishing spot but I haven't seen any msm articles actually quantify what popular means in context. I think there are some WS members who read "popular" and imagine a place that gets many human visitors a day.
My educated guess is that there were probably many days last summer where no humans set foot in the park. People who go fishing mostly seem to me to be doing it as a rationalisation to sit in a nice area, enjoying a nice day (I'm so shameless I just do it...). In order to uphold the rationalisation, they feel they have to go where they might actually have a chance to, you know, catch a fish worth keeping. Last summer, that was not 7 Bridges. The water was really low, which meant that the water temperature was high and the fishing would have been really bad.
There would be no reason for pheasant hunters to go to 7 Bridges park, it's the wrong habitat for pheasant.
During the various deer hunting seasons (there's something like 10 different ones, no kidding), there were probably a total of 5 to 10 different groups of hunters in the park during the entire season. So maybe a total of 10-30 people overall. And they would not all cover the same ground.
Seven Bridges would not be a good place to catch people making meth because it's a dead end. Too easy for LE to set up a blockade and catch culprits. Meth makers mostly prefer places that have at least two exits. They are generally desperate and drug addled people but even a very dim bulb can see that setting up to cook where LE can trap you with a single vehicle is not a good idea.
The final potential group of users would be teens partying. Here, common sense flies out the window. Most teens, so far as I can see, have precious little in the way of strategic thinking ability. They acquire it by being outwitted. There may have been a kegger every weekend at 7 Bridges but people at keggers stick close to the keg. That's why they are there. And those kegs are heavy, not the sort of thing you carry off into the woods. You leave it in the back of your brother's old beater pickup truck.
If LE comes, kegger attendees scatter into the forest but they don't go far. They don't want to get poison ivy and they want to be close enough to know when it is safe to come out again.
I would be surprised if LE finds anyone who walked within 50 feet of where the girls' bodies were found between 13 July and 5 December.
I hope that gives a clearer idea of what "popular" means in this context.
