Bill Zimmerman wants to ensnare and imprison you — temporarily. He wants to confuse, frustrate and maybe even frighten you — a little.

Then he wants to send you home from Bi-Zi Farms in Brush Prairie happy, with a beautiful orange globe. Whether you doll it up with a smiling or scary face to show the neighborhood, or scoop out the insides and cook it into sweet-and-tangy pie filling, is entirely up to you.

October is pumpkin-picking season, as well as picking-your-way-through-mazes season, in Clark County. Several local farms are opening their doors and their fields to families and other fun-seekers eager to tease their senses with all that colorful, yummy goodness, as well as their brains with all those corny corridors.

“I really want to make mazes that are challenging for people,” Zimmerman said. “If you have it done in just a few minutes, that’s no fun.”

It was most gratifying to build five identical “traffic circles,” each met by four passageways, into one labyrinth a few years back, he said; it was far more delightfully puzzling than he’d expected. Also cool was a super-long “grand hallway” with eight smaller corridors leading away to goodness-knows-where; people found it tough to tell the ones they’d explored from the ones they hadn’t yet, he said. Anytime his visitors throw up their hands and happily start over, he said, he knows he’s succeeded.
