YOU wouldn't know from looking at it, but Christine Roberts' fence has seen more than its fair share of bumps and scrapes in the past 21 years.

Situated on a sharp corner in the middle of Longford's Targa Tasmania stage, Mrs Roberts' house is located in the centre of the action.

But being close to the action also means being close to the danger.

One year, Mrs Roberts recalls, Peter Brock lost control of his car and ended up reversing onto their footpath.

"We had his tyre-marks on the footpath for quite a few years," she said.

"There's been a bit of action here in past years, a Porsche going through the front fence and lots of mishaps out the front.

"I get a bit nervous, but I'm OK. It's fun."

Mrs Roberts was enjoying a barbecue with some friends in her front yard on Wednesday, letting out the occasional gasp or cheer as the cars flew past.

"It's just a lovely day to have friends around. Next year will be bigger and better for us," she said.

"Usually we have platters and lots and lots of food, but today it's more low key."
