We found this sign on the Metropolitan Branch Trail in Northeast DC, where we sometimes go to look for murals. It was posted by the Washington Area Bicyclist Association, presumably about safety on the trail, but we couldn’t figure out what it said. There was nothing on their website to give any clues.
NOTE: Thanks to David, I checked, and it does appear to be in Amharic, which makes sense due to the large Ethiopian and Eritrean communities in DC. Tim thinks there were other signs along the trail, so perhaps they were in other relevant languages such as Spanish.
Best to view in "Original" because other versions resized by PBase are decidedly unsharp.
Enjoying the lantana, posted earlier:
