I do live without a car. I live in the middle of nowhere and have no public transport. It is very hard. Everything has to be carefully planned. DH has the car to get to work, i walk DD to the school bus stop. Groceries are done once a month when hubby has the time to trip into Melb for them. Urgent supplies, i rely on the kindness of friends passing thru town. It is a tiny community so anyone travelling into the city always checks to see if anyone needs anything while they are there.
But a second car is at the top of our savings list, as it is just too hard these days. Also have bub #3 on the way.
