When I arrived at UC Davis Rod was generous with his enthusiasm for our nascent cosmology program. He would show up at my office door at random moments with some question or other about cosmology. Those were extremely busy times for me and my normal response to random visitors was to set up a time to meet in the future that was more convenient for me. However, Rod's questions were so interesting and he was so much fun to talk with that I would usually just stop what I was doing and launch right into the conversation. Those were great times, that have left me with very fond memories of Rod.
