LOL. In Youngstown, I think all 20 places would be scattered throughout Mill Creek Park.
1. On the Silver bridge: (or Suspension bridge... or Cinderella bridge... it has a few different names)
2. On the terrace overlooking Lake Glacier:
3. At one of these entrances to the rose garden:
4. On one of these many secluded paths in Fellows Gardens:
5. On this little bridge by the Lake Glacier boat house:
6. Down the road from the boat house, but still overlooking Lake Glacier:
I'm sure there are plenty more, but I'm not familiar enough with the park to say where they are, and I'm sure you get the idea.
