I was in one a week or two back, scanning for DWEs the old-fashioned way (thank the Far God for Jameson's Cobra!).
Looked for systems in Famine state in eddb, started to fly from system to system, had not too much trouble finding a Distribution Centre (I hadn't done this in a long time, and now I know why) once I remembered that they were POIs, not USSs.
Once I found one I scored one DWE drop in forty minutes. What was that I was saying about Jameson's Cobra?
