Sorry about the links;
here are the correct ones
for Canada Border
Contact RCMP for DU violations
Contact local Municapalities for maps
You can go to Google maps for a satellite view
and go back to canada goose hunting chat index for some old posts that touch on some of your questions.
Remember when you go to Saskatchewan..it is not a slam dunk..it takes precision scouting by the moment and field opps change by the hour and competition is heavy from guided hunts as the geese will be in their fields first and you might wait for the geese to move on to hospitable farmers.
Treat the farmers with respect and useful gifts of appreciation.. no half tracks and trailers...and take back home what you shoot..spend lots of money to help the local business economy..dress warmly..bring the right gear for the situation..
Scout fast and efficient and don't boast in local bars..try to get proper permission..snow geese are not dumb and may not feed in the same fields consistently
Good Luck and take the time to learn
