WENDY PIERRO/Acorn Newspapers PERFECT BALANCE—Iain Paterson of Thousand Oaks rides his "muni", a mountain unicycle, at Conejo Creek Park. Paterson was at the park last Thursday with some friends practicing hops, jumps and obstacles. They began on mountain bikes and took up the muni about eight months ago, looking for a new challenge. "It makes you feel like a kid again" says Paterson.
