After Maniac left the McNab house where did Maniac sleep, and what did Maniac eat?

From the text:

He slept in the park that night, and for the next dozen or so. Sometimes in the buffalo shed; other times the band shell benches or the pavilion. The nights were warm now. June was on the way.

He ate when and where he could. For apples and carrots and day-old hamburger buns, you couldn't beat the deer and buffalo pens. A new Acme had opened, and the bakery section always had a tray of free samples sitting on the counter.
