I have three from Safeway that I got on my first ever shopping trip in Boulder. It felt like the thing to do. I love the Safeway ones because they're tall, but the handles are a little too long to comfortably carry at my sides. I usually end up with a collection of them at work because we have a kitchen and I bring my groceries in weekly.
At the pet store we have biodegradable bags made of corn. They suck because they're really weak, but it's Boulder so we rarely use them.
I want that green "my bag makes me better than you." That, is sooo Boulder!
