We got the same line of questioning at the border. Looks like you stopped at the Sunoco gas station at the Champlain exit. Best chicken ever. If you get there on a Friday they have fresh perch too.
We did a 750 mile loop around Lac St Jean. Started in Beaupre, drove out of the rain on Thursday. Most trails were perfect but some sloppy due to all the snow they got. We were winging it too, no issues. Although the Casino in La Malbaie was closed which we didn't know until we were already checked in. For the most part places were ignoring the vaccine passport requirement to eat which was refreshing. One place though refused to serve us because we didn't have the correct app that shows a specific QR code. Apparently Canadians use a different app than the ArriveCAN app we had to use. I probably looked annoyed and started getting dressed to leave when the manager came over and told us to calm down they would serve us. Just so nuts up there with the mandates. Definitely a different vibe than in the US. The more remote you got the less people seemed to care about masks, etc.
Anyway, we ended our trip a day early because of the storm that was coming. Been there done that before.
