"What are you going to do, I mean, how are they ever going to catch someone. It’s probably kids painting the sidewalk. Big deal,” Welch said.

Crews have been out six times in the past few weeks. They said the culprit is spray painting faster than city crews can remove the graffiti.

In one instance, the vandal taunted the cleanup crews by writing “nice try” after they cleaned up some graffiti.

"I don't want cops sitting out waiting to catch some kids with a can of spray paint,” Welch said.

The city of Santa Fe said residents can report graffiti by calling (505)-955-2255 or by e-mailing graffitihotline2253@santafenm.gov.
