Nice, but its kind of tough to schlepp all this along on an MTB through
dirt and stuff.


You don't drag the computah with you. You take along a GPS and a data
logger or GPS tracker. The data logger collects the NMEA-0183 data
from the GPS. You play it back to the VisualGPS program(s) when you
get home (or in your vehicle if you bring along a laptop).

The big problem is battery life. The pocket size data loggers are
designed to sample the GPS data, while you probably want continuous
data collection. You might need an external battery.
