Wow, I hadn't heard about Adreamisborn... that one really saddens me (just as much as LITF)
I loved watching that horse run at Bay Meadows...
I found this page:
http://flyingfilly.com/good-bye_2006.htm that lists pretty much all confirmed deaths this year... amazingly long and depressing list...
Let's all hope that the list for 2007 is much, much shorter...
