Sorry but you're wrong on that one. Scenario#1. I went to Vances Resort in Spanish, ON, it's located in FMZ 14, only allowed 2 per day, 4 in possession. If you go up the Spanish river about 1 km you enter FMZ 10 where you are allowed 4 in possession. The CO's see people going back and forth all day, no one gets charged.
Scenario #2, You go and fish Simcoe for 2 days and catch 100 perch, go home on the 2nd day and you live in Peterboro or anywhere in FMZ 16 that has a limit of 50. You don't get charged. Some of the Americans that come to Simcoe in the winter have to travel back through lower limit zones, they don't get charged either.
