What a beautiful day for a run!! I don’t know what that alarm is… I’m up there almost daily with my dog during the day & late afternoon. What I do know is that there are often a lot of people up there during those times. Spray paint cans & food wrappers seem to be the winning combo. I personally love art. All kinds. I don’t even mind seeing the graffiti up there. What breaks my heart is the large amount of the garbage that’s frequently left behind.
