There used to be a big supermarket I could walk to in the same shopping center as Little Caesars, but they closed that store, so neither of the two closest groceries are within walking distance for me anymore. When they closed, I couldn't even get fresh milk or lunchmeat anywhere closer. That's changed at least, but there's still no fresh fruit anywhere near me. And of course my brand selection and varieties of products are now severely limited, can't find a lot of things I liked and used to buy regularly.
Even with the train, I still have to walk another couple of blocks through parking lots just to get the groceries. And the grocery stores are those everything under one roof type, so there's more walking. I'm usually worn out before I leave the store.
