Maps:
The most important map:
Bookmarking the perimeter outline in Google Maps might be one of the most useful wayfinding tools for your perimeter exploration.
Note: You’ll want to get that link open in the actual Google Maps app, not in a web browser. On some mobile devices, that might require copying and pasting the link into an SMS text message to yourself or someone else, and then clicking the link from within that sent text message. If you have trouble on an iPhone, try setting your default web browser to Safari before clicking on the link. Then click the button to “open in Google Maps”
