Extra precautions need to be taken. Tyres - check. Petrol - check. GPS - check. Cash - check.
We travel at a sedate sixty k's to the freeway, and then everyone sinks their foot to the floor. Well, everyone except that one stubborn person in the right hand lane still doing 50km/h.
After a few deep breaths and some calming trance music, all is well. We're ready for life in the slower lane once we have found our turnoff. And it is worth it, because towns in the Adelaide Hills are a pleasure to visit.
Cattle and sheep stare insolently at you as you pass by. A country deli which doesn't seem to have changed in 30 years turns up a deliciously fresh local bakery pie. And stopping for a drink in the local pub reminds you of the pleasurable time when pokies didn't exist in South Australia.
Nairne is a bit like that. If you call through on a Saturday afternoon you may wonder what's on in Adelaide, because it is sometimes rather quiet. But the locals are more than likely just watching the footy at the local oval.
There are many quaint old buildings giving Nairne a village feel - the local pubs have a typical 19th century exterior style and always make me want to explore inside.
A sign opposite the Millers Arms Hotel explains some of the local history, while a short stroll down the side street brings you to the Albert Mill, a charming and well maintained old building now used as a Bed and Breakfast business.
If your idea of where to visit in Australia is an Adelaide Hills winery, then Nairne has its own, too. The Howard Vineyard has a moderately large range of varieties available, and its dining facilities have had good reviews.
Just be aware that there is a charge for tasting wines on weekends and public holidays, and for larger groups. It's not a practice that I support, but each winery has to make its own decisions on that.
At the far end of town is the disused Chapman's smallgoods factory. I imagine that most residents just wish that the earth would open up and let it disappear, but it probably won't be long before it is razed.
If you have kids on board, there is a modest skate park with basketball hoops just of the main street. That might give you a few minutes to explore the former church on sale - a pretty building with character which could benefit from an imaginative conversion. Perhaps you could even run a business from it?
