You have to start somewhere and it's only a reccie after all.
The amount of miles that we covered on our reccie was ridiculous, but you have to make sure you are making the right decision for you and your family.
There are a lot of things to consider, where you are going to work, cost of renting and buying if you you like the area and surrounding areas, schooling if it's a factor, cost of living as every area has their own pricing system when it comes to groceries .... we live in Port Noarlunga and don't shop in the area for the big stuff, we go elsewhere, for want of a better word, to the cheaper areas, as it helps to keep shopping costs down.
You'll find your feet and know for yourselves where you want to call home. A reccie and then renting is always a great way to start.
The very best of luck to you.
