My only worry is that she has gone missing on her own before, and was off her meds. It's just so tough to get a handle on her frame of mind that night. I think both avenues of investigation (leaving on her own and being lured to meet someone) are about equal at this point, just my own thoughts. It is troublesome that her car has not been found yet. I'm also glad they are searching Rockland County in NY now, that is just a few minutes drive from Montvale. Being in northern NJ, space is at a premium, so I would've thought her car would've been found by now, in a parking lot, or abandoned somewhere, or at least seen somewhere.
I'm glad the family listed good places to search on the GO Fund site...hotel parking lots, park and ride lots, train stations, etc. They also said she loved to hike - I'm sure they've checked the local hiking spots for her car, Ramapo Reservation etc. I wonder if they've checked Harriman State Park. Those places are patrolled pretty well, I feel like if her car was parked there somewhere, it would've been found by now. I grew up about 5 minutes from where Meg lived and I currently live right between Oakland and Montvale. There are a lot of great hiking trails and mountains in this area. Not sure why she would drive to a hiking spot at 3 a.m. but everything needs to be checked.
