Canada is strong. Together with our allies, we are even stronger.
Good to meet with you in France, President Macron. The friendship between our two countries is the envy of the world.

I swear they just like blocking the bike lane for fun. The bike lane is often treated as free space for signage. Note that the right turn lane which cars share is not blocked. (video is sped up) 1/2

(electric) Bike ride through Mira Mesa (San Diego, California) today. Testing out my new insta360. youtu.be/3kxgStQCqGw I don't think this is the best mounting spot :/
BTW, it's a 360 video so you should be able to rotate the camera.
