First it was red balloons tied to sewer grates.

Now a Pennywise headshot is peeking out of a downtown Tucson storm drain near Broadway and Stone Avenue.

Sightings of red balloons have been reported across the country since days before this weekend’s movie opened. “It” earned about $117 million over the weekend, a record-setting opening for a horror movie.
