I know this is a little late, but I haven't been on the site in a while and came accross this thread...
I worked with Dave both during PMT and Iraq. He was an outstanding man all around. I can't say it any better. The SF community and his family lost a wonderful leader and father.
I remember seeing him over at the AOB one day sweating his ass off helping the mechanics we had get a truck together for a mission, and just seeing him laugh and joke while getting this truck together in no shade in the middle of June and just thinking "this dude is nutts!!!" lol
RIP Dave
