I've know Mark most of my adult life. He's my best friend and brother. He's was the Best Man in my wedding (both of them - LOL). I will never forget the phone call I got from him Thursday while I sat in rush hour traffic in DC. I hate to do this because I'm sure I will miss someone but ... I want to thank a few people for all they did (and are still doing). HNT - specifically Lisa D. - you are the best - Mark remembers your voice and your run to hug him. Sean V. - if I could have gotten here sooner
