One thing I love about living in a bustling metropolis is that you are never far from a corner store. ("Bodega" for those of you in NYC)
My favorite corner store is located one block east and has most anything I could need at a moment's notice, cooking-wise anyway. It is clean and well maintained, the proprietors are always pleasant and the prices are cheap.
It is comforting to know that if i start cooking something and suddenly realize i need:
I can pick it up in less than a 5 minute walk from my front door. And if I'm out of cash I will most likely be able to raid the change jar for enough money to pay for the small thing I need.
I think more often than not, if I had to get in car to make these purchases I would probably end up scrapping my project.
