Thank you for agreeing with me. And I agree, the main focus should be on collecting data that is missing such as trails, woods roads, benches, parking lots...etc. 

I edited it originally for consistency. Westchester County manages 25+ parks, each with wide variety of features/uses. If some are tagged as parks while others nature reserve, it creates some inconsistency.

And in Westchester at least, I've been trying to sort of standardize certain tag formats. For example with trail names I'll use 'Quarry Trail (blue)', as an example. If you are hiking, just 'Quarry Trail' does not help much, so also having the blaze color in parentheses is helpful from a hikers perspective. 

And some parks can be subject to debate. Like Rockefeller State Park I did not touch at all. There are lot of carriage roads and some fields, but a huge portion of the park is natural woods. Or there is Ridge Road which has a few sports fields and picnic areas, but the same thing, a lot of woods and some hiking trails. I think the land use would be a better representation of what is in the park. For example if a separate area is drawn and then tagged as forest, or wetland, or meadow, or field, that can provide a lot more information to someone that is looking on the map.
