Thanks, Monster 12 for your insights. On Friday afternoon, I finally drove on Briar Hill Rd. and Newburg Rd. Saw the flowers/shrine by the road and the wooden post gate with a large Keep Out sign at the property where Chelsea was found. Very, very sad to see the area. Some random thoughts: many large, beautiful homes in the general area. It is slightly rolling, not flat and actually a very pretty area. I noticed the rr tracks heading off Briar Hill toward where Chelsea was found and the area beside it looked smooth, wide and easily accessible, just like the pictures of the day she was found with the detectives. I did notice along Newburg Rd. the ground by the rr tracks is more slanting and has more stones on the side. Not as good driving right there by those tracks. The area is isolated but there are still homes around, although early morning most people were sleeping. It would be so dark to drive without lights on and it would look strange to see a car with lights driving by the tracks. There are people who work nights, come home late from parties, etc. Newburg Rd. is a 'washboard' road, really rough as it is dirt and so many holes, low areas that it is very hard to drive and one can only go slowly.
Another item of interest. I spoke with a friend who lives near the intersection of Newburg and Grafton Rd. She used to take her dog for walks down Newburg and close to the area where Chelsea was found. A couple years ago or so she said she felt uncomfortable as she noticed more cars and people she didn't recognize, who looked 'unsavory' on the roads. When I pressed her why 'unsavory', she couldn't say why. She said she felt creeped out and decided she shouldn't walk that way any more and started going to the Willow Metro Park, where she felt safer. I thought about the possible fighting among the boys from the school, etc. in the area possible being back in there.
I asked another friend who has a friend who lives two homes away from the party on Post Rd. about the noise and crowds, etc. attending parties there and did the neighbors complain. She said not really as the party was out far enough from the road and other than parking, and increased traffic, there were no major concerns. I would say neighbors were quite tolerant.
My other friend who lives close to the site where Chelsea was found told me not to play detective (I was asking her a lot of questions), as she and her husband are friends of the Sheriff and have complete confidence in him and the department. They will find who did this. I was encouraged by her remarks.
All of these items don't really help but I wanted to share.
