Here in UK Bowling Greens are accepted as wayspot. What's more, when entering the website, one of the valid examples is of a bowling green. Any explanation why it was rejected?
"The Bainfield Bowling and Social Club is situated in the West side of Edinburgh on Hutchison Crossway just off Gorgie Road. It is one of the largest bowling clubs in the UK with two outdoor greens. This is the second outdoor green."
"Please use Google MAPS (satellite) instead of Google Street View to check the existence of the bowling club. This type of sports club have already been accepted as a stop in other parts of the city. The stop is accessible from a pedestrian street next to the bowling club. It is NOT a NATURAL feature. It is NOT a DUPLICATE of the other stop. Thank you."
