Very very sad. He had a wonderful personality and had a great joy and appreciation for life.
I never personally met him but my sister met him and palled around with him at a convention, moonlight rising she said he was very down to earth with a killer sense of humor.

I knew he had heart problems because he collapsed at a con a few years back and was rushed to the hospital, he was poorly for months having to cancel his con tour for that year. I just didn't realize his condition was so severe and he had never gotten over the ailment.
