  I meant Street Side images obviously. It's easy to call it Street View since I use it way more for private use and they both start with "street." 
  
  "I am free to hike down the gulch at the bridge edge access and recreate."
  
  You should do it then and map it  with Mappilary. It would be an easy to prove it. Although like I said, even if there is a small path between the houses and the gully for you to walk down it doesn't automatically make it a park. Plenty of places do that are/aren't owned by cities and they aren't parks. Notice to you said that you said you "could." Until you actually do, you don't know how far the path goes or its purpose. Your just assuming you do to prove a point that has no other supporting evidence. If you do actually hike down it and it is a park fine, but there should be a standard of "I think that's what it is, maybe, but I only drive by there and haven't actually been there, but I'll map it that way anyway." 
  
  "This is public land. Ergo, park. Resolve this."
  
  Public land does not equal park. Except in cases where it does. But there's plenty of "public land" out there that's not parks. Let alone tagged as them in OSM. There's no "this tag is for everything that's public land" description on the park wiki page.
