There are countless thousands of baseball fields in the United States, and no two are alike.
Baseball is the only major sport with no strict guidelines about the size of the playing field. While major league stadiums all have reasonably similar dimensions, the smaller stadiums and community parks where average people play the game can be truly bizarre. I played at a field as a kid with a pond about 400 feet deep in centerfield. (A guy on my team once hit one all the way out there. He got a double. He was very slow.)
There are places like that all around this country and people on Reddit’s /r/baseball forum have been sharing all the ones they know about.
