I’m still working on the best solution for this, but the idea is that my location will be shared on this page to the people I trust the most. At some point there will be accounts on this site and access will be granted only to friends and family.
In addition I’ll be using the ESR (EastSleepRide) app to record my routes. The app also has a service called “CrashLight” that will call/text/email up to 3 contacts in the event that the app detects a crash! Heaven forbid, of course.
