Movie name with Worlds Fair


I'm trying to remember the title to the movie with the kid trying to find a special top and his family goes to the worlds fair and he buys one from the gypsy. I think it was made in the late 80's, but not sure. They live next door to a bunch of hillbillies with dogs and they're always fighting with them.

It Runs in the Family (1994), also known as ''My Summer Story''
“Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.”

That's the one! Thanks a lot.
