ALLOUEZ, Wis.

No need to look twice, that really is a velociraptor peering over the fence at the corner of MacArthur Street and Kalb Avenue in Allouez.

Signs warn passers-by of the dangers that lurk beyond Jim Brisbane’s tall wooden fence, USA Today Network- Wisconsin recently reported. One sign shows a yellow circle and the silhouette of a Tyrannosaurus rex and the words “Jurassic Park.”

Swinging open the gate reveals a park “greeter” (a mannequin) and two cheerfully waving skeletons lounging in chairs. There is also a “hatchery” full of baby T. rexes and close by is a watchful pterodactyl.

“I never get tired of looking at this yard,” Brisbane said.

Brisbane, now 72, began gardening 20 years ago after his therapist suggested he needed a hobby to help with his post-traumatic stress disorder. Brisbane served in Vietnam as a member of the Army in 1967.

For years he planted, hauled plants and supplies and maintained his yard. Along the way he installed statues of turtles, Sasquatches, sea gulls and bears.

After the death of his wife, Connie, three years ago, he continued to look for ways to improve his yard.

The idea for Allouez’s Jurassic Park grew from online searches.

“I wanted to get away from the same old routine of bird baths and deer laying (down),” he said.

He achieved that with velociraptors, T. rexes, and pterodactyls.

In 2016, the first part of his vision was complete.

This year the toothy dinosaurs have been joined by mannequins and car doors with decals from the Jurassic Park movie.

Although it would be hard to tell from his yard, Brisbane said he is not a fan of the 1993 movie that kicked off the Jurassic Park franchise.

“I mean there are a lot of things in there that if I was going to make the movie it would be totally different,” he said.

Brisbane prefers people view his dinosaurs from outside the fence when he is not around.

“Everybody who comes through this yard leaves with a smile or a laugh,” he said.

When it is time to close Jurassic Park for the year, everything gets put away and he begins planning for next year.

“I’m retired and I know a lot of people when they retire and they become couch potatoes and they have no interest whatsoever and they don’t use their creativity,” Brisbane said.

Neighbor Jon Reineke’s 4-year-old son enjoys visiting Brisbane’s yard.

“I think it’s great. I think it’s a lot of fun,” Reineke said.

Working in his yard soothes Brisbane and helps with the PTSD. Once the lawn decorations are in place, he devotes his time to landscaping and caring for his yard.

“When I put them in, I always say a little prayer ‘I hope you make it,’” he said of his plants.

Lee Hansen, who has lived on Kalb Avenue for 40 years, called Brisbane’s home the “Allouez Disneyland.” Hansen’s yard is known for its roses.

“I think it’s great for the community and great for him,” Hansen said.
