On Friday evening my husband and I were crossing the street at Pioneer Square and were accosted by approximately 8 college age youth for money. They were wearing green T-shirts that said "Mercy" on them. They flashed camera's in our face, held up personal devices to take our photos, and shoved buckets at us chanting "any amount will help". We are seniors (67 and 70) and short of being mugged, we have only experienced this with gypsies in foreign countries. There is no police presence here. The visitors center was closed. The staff at the visitors center had ignored us when we stopped in earlier. When we reported this to our hotel, they just shrugged their shoulders. You are on your own baby in the heart of Portland!
