OROVILLE, Calif. -

An expert on the mysterious creature Bigfoot spoke Wednesday at the Lake Oroville Visitors Center, drawing a huge crowd.

Zoologist Ron Brown, who first started studying Bigfoot while attending UC Berkeley in the early 1970s, presented to a crowd of more than 160 people about evidence of Bigfoot and the legitimacy of sightings.

In fact, Brown himself says he's seen the creature in the area.

"I have actually spotted the animal outside of Oroville with my own eyes," he said.

He also says there have been dozens of documented sightings nearby.

"You know, in 1969 on Table Mountain 11 people saw Bigfoot," he said. "And off of Black Bart Road also. Some people on the lake had sighting, while they're on the lake, seeing it on the shore."

Brown also brought with him alleged castings of the elusive animal's feet.

Whether it can be confirmed or not that Bigfoot is a real ape-like creature which roams North America, Brown likes to show people his findings and let them decide for themselves.

"Is it real, is it not real? I invite people to examine the evidence and that's what I'm doing here tonight."

Brown was invited to present as part of the Summer Speaker Series at the Lake Oroville Visitor Center, and has done so in recent years as well.

His visit typically draws the biggest crowd of the annual speaker series.
