Self snipped
Based on #4 and #6, we can rule out RFG being concerned about his physical safety causing #3.
The route between Raystown Lake has about 12 miles where it is nothing forests and farms. It would take LE some time to responded even with a call. RFG probably drove that stretch twice. It looks like from a map, that there would be about 15-20 miles without coverage each way (including part of Route 22).

So, if RFG is concerned, on 4/14, about his safety, he is taking a gigantic risk. It would also be difficult (if not impossible) to follow him on this route, and not be spotted. He didn't report that there was a threat or that anyone was following him. Yet, on the morning of 4/14, he was acting unusually at the Prison Board meeting.
On 4/15, RFG, if he is meeting someone, doesn't leave any notes to where he will be or who he will be meeting. Since he did the Lewisburg search on his office computer, and was in the office on 4/14, he could have left the information there. He also chose a route that was remote, and included a cell phone "dead zone," even though there was an alternative route (I-80), that both had cell coverage and was patrolled by the PSP.
Whatever was bothering RFG, it was not a physical threat to his safety.
