LEBANON — Dan and Donna Behymer love the Christmas season. Each year, their home is decorated in dazzling colored lights and amazing hand-built displays. So what better way to celebrate Christmas, the Behymers decided, than to invite a Grinch into their home?

As the pièce de resistance for their annual Christmas decorations, the Behymers built a “Whoville” house — a two-story facade designed to replicate the homes of the Christmas-loving village in the Dr. Seuss classic “How the Grinch Stole Christmas.”

“We try to do something unique every year,” Dan said. “We thought up the Whoville house while camping at the end of August. We weren’t sure if we could make it in time for Christmas.”

The Behymers have been adding increasingly elaborate decorations since they moved to their current home in 2001. Although they are originally from the area, the couple had been living in California, where Dan said elaborate house decorations are everywhere. They built their first decoration — a plywood, free-standing Charlie Brown and Snoopy — in 1998. Every year since they have added something to the display, from a sled that can seat a large family to nutcrackers that guard their garage.

“We were having a hard time getting the entire family together for Thanksgiving, so we created our own holiday,” Dan said. “The Saturday after Thanksgiving has become the Grand Holiday Lighting Day and all the family comes for it.”

The Whoville House is made of a two-story wooden frame that connects to the front of the Behymer home. Attached to this frame are removable fiberglass panels that Donna painted in a “grinchy green,” designed to replicate the oddly shaped homes that Seuss drew in his book.

“Our grandchildren love us,” Donna said. “They think it’s like a big playground.”

After the construction phase, Dan and Donna begin setting up decorations around Halloween. The hardest part is stringing lights around the 24-foot tall (and growing) evergreen trees on the side of their house.

The Behymers’ next decoration may be the most elaborate yet. Dan’s 4-year-old granddaughter has requested a flying reindeer above the 24-foot trees that have already provided such challenges to decorate.

“We’re already trying to come up with a way to do it,” Donna said. “She wants flying reindeer.”
