I know several here knew Bob Morrison from his posts in this ng. I realized recently that I hadn't heard from him in a while (we had corresponded a fair bit off-line) and I checked his blog and saw nothing recent. So, I did a little searching and it appears that Bob succumbed to Leukemia early this year. I'm not 100% sure of this as I couldn't find an actual obituary, but this seems fairly definiting.
