Divide your notebook page into four quadrants by drawing a horizontal line and vertical line on page.
By doing this you should have four boxes.
Now create headers for each box.
In first box, the header should read: images; second box, sounds and smells, third box, things in action and fourth box any words seen (can be on buildings, billboards, people's tee shirts, posters, street signs, any signage)
Go for walk. Write down what you see, hear, taste touch smell , according to the categories of each box.
From the lists, create a poem with cascading lines. Enjoy your walk.
After you write yours, then read Frank O'Hara's "A Step Away from Them." I love his Lunch Poems collection.
