Firehouse primary on short notice is a less-than-ideal situation. At a glance, it looks like the committee managed to find a location in far southside (Lawrenceville), one in petersburg, one in south richmond (with good bus access), one in north richmond, and one in eastern henrico (just off I-64). Polling locations in every neighborhood are obviously preferable, but given that wasn't an option (for off-schedule primaries, party committees have to arrange their own logistics), their locations seem fairly reasonable to me considering that the most of the population of the district lives fairly centrally and that city residents are less likely to have a car and be able to drive to a distant location. They could have just picked one location and made everyone go there, but they didn't.
