bike bags?

Also, re: securing bikes w/o a bike rack?

How about a light post? Or at a grocery store, sometimes they have racks outside to hold the carts. You need to be careful there so the bike / lock isn't in the way of getting carts in and out of those corrals, but it can work. But definitely lock the bike to something!

And on the pics above - I wouldn't put a container filled with groceries on the handlebars. I don't think you'll like the way the bike handles if you start adding heavy items there; for grocery shopping I really think panniers are the way to go.
