Our #1 guy this morning on the Seattle Hog List has sent 307
NMEA-string (LONG) packets today.

I've sent 36 base-91 (SHORT) packets, 14 of which were dupes as
received by the SEA node right in Seattle, so really only 22 unique
packets during my 50-minute commute made it to Seattle.  That seems
reasonable for a SmartBeaconing(tm) setup.  I'm currently #42 but
I'll drop further down the list during the day because I'm not
transmitting while parked:
