I like the idea of using animal wire for tomato cages. Growing up my father planted 400 tomato plants a year and it was my job to keep them watered, tied up to an old tobacco stick and pick them as they ripened. When you have 400 tomato plants ripening at the same time you use a wheelbarrow to pick them. About every 2 days he would take them to work in the back of his pickup truck. He never sold them, he planted them so I had to work to keep me out of trouble. Seems to have worked.
