The Granny Cart

Carlos bought me what I like to call a granny cart at the flea market a few months ago.  He didn't like to think of me hauling groceries up 4 flights of stairs, and in gratitude I have used it ever since.  I keep the granny cart in my car and use it to take the grocery bags from my car up the elevator to my apartment.  It's much easier.
Today, I got it into my head to walk to the store with the granny cart and granny cart the groceries all the way home.  Trader Joe's is about a 20 minute walk from my house, and I thought, "well, since I want to exercise, and I need a few things from the store, I'll kill two birds with one granny cart."  No big deal, right?
Wrong.
It took me twice the time I thought it would.  Apparently, I should have factored in having to wheel the cart  into my calculations.  Part of the trip is over gravel and dirt, so you can imagine the rickety, rackety shaking of the poor wire basket on wheels.  Some lady wanted to touch my pineapple.  A shirtless man in his sixties on a bike with the butt of a cigarette stuck between his lips veered way too close to the cart and me.  And the traffic lights change much too quickly for me and my cart to get across the street.
Needless to say, it was an adventure.
In the end, I did get my groceries, and I got my exercise.
I'm not giving up on this idea.  But next time I will plan better.
