Here is a jpg of the missing poster, I have a larger pdf version. If you want to help by printing and distributing posters, email me directly at email@example.com, and I'll get a file to you.
If you have people in Montana, Idaho, Oregon especially, would you send this their way? If he did "walk away from home" he MIGHT head that way (just my guess), he was a fishing guide there.
Here is the link posted by Larry's niece, Lisa, on craigslist. It's where I got the info to make the poster. The other link is to my facebook page, where I'll be posting updates and info. I have changed my status so you don't have to "friend" me to see when something new is published there.
