Bob and I live a town apart and I would always talk with him about the latest deals we found at our local stores or smaller shows. How he would specifically venture in on the days the manager bought collections so he could get an early look. Each year our store would have a 50% off sale and we were usually the first two in the door, digging through boxes, chatting with each other, showing off what we found, and even trading once the dust settled.
I did not know him long (compared to others here), or outside of comics, but, to me, he was a rare "genuinely nice" person who was very passionate about the hobby. He will be missed; RIP.
