I did complete the Addendum at 2010 summer's end. Its proper name is "The Caboose" and it follows my previously released Memoirs & Musings. I had it posted here on Lady Wolf's Notes for a while, but have taken it down to save space on the blog. I'll be happy to postal mail a hard copy of it to anyone who requests it.
"The Caboose" was fun to write ... is light-hearted and a pretty good read.
