Have you tried knocking on the door to get into the house? Also: Try to use the bacon to get a hint.

Knock on the door and use invisibility

what house? all i see is a slide, a sandbox, and a toy truck. is the house elsewhere? thought i'd been in all

There are two different telephone poles you can climb up to slide over to different areas. I think climbed up the telephone pole near Boyd's house.

There's also another pole near the book depository. Try that one.
