I was looking for over an hour, lol, and now I can see where you guys were, but I might have missed it as I showed up at 3pm. I went up and down that street on my Truimph, in between the warehouses, out by the river, along the railway tracks but I didn't go through the shrub line into the flats. I didn't see any parked cars so I didn't go past the treeline.
If you guys hadn't left already you were probably a stones throw away!
Lost my sunglasses but I found scads of rosehips, a strange blackberry bush, and some other berries I know nothing about.
