After checking out several GPS tracking apps I can use with my Android, I think I've settled on Real Time GPS Tracker by Greenalp (www.greenalp.com). I think I'll be able to embed a live GPS tracking map on my web site and I can also send out via text messaging or email from the road. Maps can then easily be viewed from a computer or iPad, iPhone, Android devices, etc. Still might check a couple others out but for now Greenalp is what I'm going with.
On August 14, 2013, I'm flying to Vancouver, British Columbia and beginning a 29-day, 1,880-mile bike ride from Canada to Mexico.
