Sneakers tossed onto power lines? In Portland, something else is apparently taking their place. Sex toys.

Images of the phenomenon have circulated on social media for a few weeks. One tweet Monday read: "#Portland: All fun & games until your 6 yr old child asks, 'What are those?' as they point to the dildos in the sky."

Depending on the commenter, the number of suspended sex toys ranges from dozens to hundreds, but no official tally exists. People have documented examples in North, Northeast and Southeast Portland.

The Portland Office of Neighborhood Involvement has received less than 10 calls in three weeks about them, said Susan Barr, a worker at the city and county information and referral center. People have reported them on Comcast and CenturyLink lines, she said.
