Hi, Gracie. I am VERY familiar with the location where Audrey's vehicle was left and I am not sure what you mean by protected from view. It's very open in this area. Perhaps I am misunderstanding what you mean.
In a previous post someone mentioned (possibly you) Moreno Valley. If someone was heading to Mo Val, as we call it, they had already passed the on ramp to the 60 by the time they reached Oak Valley Parkway. Taking the 60 from the 10 leads straight to MV. Continuing on the 10 would not. You would travel though some smaller sized cities (Calimesa, Yucaipa, Redlands) and then start to get into larger cities and eventually end up in LA.
Audrey's vehicle was parked just past the ramp leading from Oak Valley Parkway onto I-10 west. That particular exit has a hotel, gas station, sport bar, and several stores just a couple of hundred yards from where the vehicle was. There is constant heavy traffic in this area. I've driven through here hundreds of times at all times of day. Even in the middle of night you are rarely alone. This is a major corridor from the desert part of So Cal and Arizona to the LA area. Around morning rush hour I've gone as slow as 25 through this area because of the heavy traffic. Usually traffic flows around 75 mph, but when there are a lot of large trucks on the road and everyone is commuting to the LA area it gets backed up. It's an exit that I feel comfortable stopping at at night. It's well lit and there are always people around.
