A campaign called 'Poop Smart Skagit' has some advice before you visit the tulips this season.

The Skagit Valley Tulip Festival is in full swing with blooms decorating fields in Skagit County. But officials are warning of issues related to human waste that could spoil your visit.

The festival is one of the most picturesque event in Washington every year — drawing visitors from around the world.

“You see something here that you really can't see outside of Holland, so it’s truly unique,” Tulip grower Brent Roozen explained. “It's a wonderful experience and we think it's something everyone should see at least once.”

There are flowers and tulips of just about every color blooming all month long.

“If I hear wow, I've done my job." Jeannette DeGoede explained. DeGoede and her husband have been running Tulip Town for decades. She said, "Over 86,000 people will come through our farm in the course of a month."

Along with all those visitors comes the traffic. And when you've got people going places, sometimes they have to go. That problem has turned into a bit of an issue and now the County Public Works Department and EPA have a public information campaign to encourage people to “Poop Smart Skagit.”

They've had issues with human waste within downtown Mount Vernon and nearby fields, which can be bad for animals and growers.

“We grow a lot of food. Not just for the county, but for the country, as well," Roozen explained.

The tulip growers try hard to minimize the impact on other fields in the community and educate visitors about the county’s agricultural significance.
