# Ankara & Eskisehir are about 200kms away long/lat wise;
#
# Ank: 39.925533, 32.866287
# Esk: 39.766193, 30.526714.
#
# That's about 2.34 diff in longitude (much less in latitude), multiply by 100,
# get rid of the floating part (round down aggressively), 200 seems like a good
# margin, that's probably within Ankara borders
#
# The API recommends calling every 5 seconds (not more frequently, please!), 30
# seems fine
#
# Coords below are from the METU hoodie :)
