Another touch I didn't take in previously.
The colored interactive map distinguishes between
which snowplows are active, and out on the roads,
and which snowplows are parked and inactive.
The named snowplows have their names regardless
of whether they are active or are parked and stationary.

If the interactive map shows a yellow snowplow,
it is active and out there working.
The grey snowplows are parked and inactive.

Glasgow has a concentration of grey, inactive snowplows at the moment.
