Another coming of age story (those are very popular for summer themed films), about a bunch of kids in the 1960's who live to play baseball day and night. This is kind of a classic now, made in the vein of A Christmas Story, with a narrator looking back on his childhood years in episodic events- battling the giant bulldog next door, swimming at the pool, the hot lifeguard, etc. This is a great one for kids especially, as it's the kind of movie that really never gets made any more. It seems like the 90's was the one decade where live action movies starring kids were considered profitable enough to make on a regular basis. You don't see much of it now.
