At others' suggestion, I created a Flickr photo album to honor Craig. You can see it, and ADD TO IT, at http://www.flickr.com/groups/craigjohnson/. Please do add to it, too, if you have any photos of Craig. The instructions for uploading photos are right there on the page, and are very easy.
P.S. You can also reach this page by going to flickr.com and searching "Craig Johnson" under "groups."
