Some fixes/improvements to Centennial Park. I think it needs some more work - I remember seeing some other barricades across roadways. It looks like they used to be accessible to automobiles, but now are intended for pedestrians.

Nashville Life Church

Removed a trail which is entirely overgrown - no longer a trail at all.

A number of changes to RCSP from survey notes and connected some footpaths to other ways (service roads, parking aisles, etc.).

Connected foot paths near picnic area restroom

Added picnic tables near Area 15 RCSP
