No sign of the guy who took him. They had my grandpa very liquored up, but he just kept saying they were ******** and there wasn't anything he could do. The motorhome just smelled like beer - a lot of beer. He slept very well last night, but doesn't remember too much.
Thanks for all the support and a BIG thanks to the Chicago guys (Greg, Tony, Tom, Andy, Neno, Chris, etc.) who helped Adam and me out during this. I can't begin to explain how much of a relief it was to first find the motorhome and find it in good shape (not all messed up inside, everything was pretty orderly) and then a few hours later to find out my grandfather was found. He was found in Chinatown, a pretty far distance from where the motorhome was located.
We'll be selling the motorhome soon and getting a GPS device on his Jeep. I think he knows that he won't be driving distances anymore, but with him living in Crivitz and us down here, it's more difficult to help him out. He's staying wit my parents this week as we figure more out, but thanks again to everyone!
