When you move to a new estate where only half of it has houses and the rest is either in the building process or vacant land.
When your children discover on the vacant blocks beside you that someone has dumped an old Kiddy Toy FWD.
When even though this 4WD Toy has texta all over it, and is falling apart with no steering wheel your kids can still see the potential. Bless them.
The above photo still makes me laugh. My eldest son is driving, with his BMX gloves on. Sons 7 and 3 have the job of pushing the '4WD'
