Runningshield - mark

In relation to an earlier post
Every time I go out of town or to a different country.
I would look for a tree, fence or even an electric post and tie a nylon string around it. The reason I do this is to leave my “Mark” A statement that “Patrick Concepcion / RunningShield " ran in this particular area”.
This time I leave my mark in BOSTON and SAN FRANCISCO.
Hopefully, when I do come back in this area after a few years my “ Patrick Concepcion / RunningShield “ Nylon string mark will still be around.
