Been a while , Heres a free skate park I made some time back. It Even has some nighttime lighting.
Location: Ammunation Rooftop

Note: This uses a modified “dt1_rd1_strm_1” base Ymap. (removes the spawning car generators on roof)
I recommend doing a search for this ymap to make sure your not already using a map that has this already. If so, running duplicate base maps in multiple resources will cause issues. Learn to merge your ymaps.
No support issues except for making sure the download is availble to everyone.
