Went all in. The place now has all the paths (even the smallest ones), benches and almost all individual trees.
Anybody visiting (or working, or studying there) could benefit on osm.org, and soon in all mobile map apps* :)
If you want to demonstrate a well mapped site, "this one hospital in Latvia" will be good for a while (they have some construction going on).
