I don't know if anyone caught this but the latest from her husband was that she made it as far as Lake Nona High School on Narcoosee but that they were waiting for more video.
Search continues for missing Belle Isle mom as new information on her vehicle emerges
It had been mentioned before that south Narcoosee is more wide-open, and it definitely is, especially once you get past the Lake Nona area. Depending on which direction she possibly went from there, there are some large WMAs that you can drive into. Bull Creek and Triple N are big for hunters and hikers (I go hiking there every now and then), there are lots of isolated roads back in there, but that's provided she even intended to go there in the first place. Each has an "official" entrance, but they don't have rangers or staff to check in with. Bull Creek has a campground/RV park at the entrance where people are kind of milling around, but that's it. Both places aren't really somewhere you 'stumble into' though, you have to know you're going there.
Split Oak is another possibility, but IIRC you don't drive back into it, there are just trailheads to park at.
Provided she made it to 192, from there on south/east there's just vast stretches of open land. It's also the back way to the east-coast beaches, but if she reached there, you think there'd be some activity or witnesses.
But who knows. Maybe she went to Lake Toho and something happened. You'd think someone would have seen something, but it's a big lake with several public access points.
