most of these small parks here look as if they should instead be landuse=grass and have the name tags removed as the names also do not look real... anyone who knows more about the site can take a look?

looks like for both stadiums here there are duplicate tags for the same two stadiums (4 tags) when there should only be 2. There are stadium tags on both the large areas encompassing the sites and there are stadium tags on the buildings for each stadium. Suggest only keeping one of the tags, perhaps the one on the buildings?

there are two tags for the casino here: relation/7673392 and relation/4599344 only one should have the casino tag on it, suggest updating the correct one to remove the duplicate information but keeping relation logic correct

looks like this is not really a airport, but if someone can confirm and update poi accordingly... no runways visible from aerials but could be a dirt field landing strip situation...

if the runway here is marked as abandoned then the airport should probably also be marked as the same...

town boundaries here looks like there is a gap, should be verified to see if it needs to be fixed

castleton boundary line here looks like a possible mistaken dragged node with this power line, anyone with knowledge of the boundary here can take a look...
