Michal Young of the Oregon Randonneurs has set up a group tracking site for Pacific Northwest randos carrying SPOT trackers at PBP: http://enroute.saunter.us/track/nwrando.html
If you’d like to add your SPOT track to the group, please contact Michal (see his original post in the SIR group on Facebook).
There should also be tracking provided by the PBP organizers, here. (under construction at the time of this writing).
Know another way to follow along from home? Please share in the comments. Thanks!
