No report for this expedition has ever been filed, but a photo was uploaded to the wiki by User:Minimalismo on 15 July, with the caption "Geohash location on july 13, for the Sint-Truiden graticule in Belgium". Confusingly, it was placed in the expedition image gallery for 12 July, with a link to a Seattle expedition.
Sint-Truiden is in the Liège, Belgium, graticule, but neither the 12 July geohash nor the 13 July one is near Sint-Truiden itself. Also, neither is particularly near a road, so we are forced to conclude that this expedition did not reach the exact coordinates for the day.
