Probably a side of Pearlridge that they'd rather you not see, the drainage ditch between phases I and II, with the Sumida Watercress Farm off to the right. Back in the day (mid 90's), I'd use the ditch pathway to cut through from work at Tower Records Aiea across the street to get to Shirokiya to pick up my issue of KOKIKU each month!
Ah, those were the days.....
