this was not a fitness station it was a bench I added. I was adding it from Go Mapp app on phone and im not sure why I said fitness station

looks like you just went really in depth mapping your house (or some random house. hopefully your house otherwise it would be kind of creepy to tag someone else's backyard recreation ground). Anyways yeah no other houses in this neighborhood tag there grass, so inconsistent.

Recreation ground... Description: An open green space for general recreation, which often includes formal or informal pitches, nets and so on. Often municipally owned, sometimes part of colleges / companies or commercially operated. Edit or translate this description. (landuse=recreation_ground)
