Good photo of the area where his car was found.
You are right--this is no time to go wading in the Susquehanna. A couple of weeks ago, it was raging out of its banks. It's a little calmer now, with the 2 week drought.
Lewisburg is a low-crime town. Very quiet, except for the occasional Bucknell beer riot.
Since Ray told the girlfriend where his destination was, I don't think he tried to pull a disappearing act. It would be very out of character for him.
He was not carjacked; no signs of foul play in the auto.
Amnesia? Sometimes it happens.
Maybe some FReeper reading this will spot Ray Gricar somewhere in the PA-NY-NJ area.
