This is what I happened upon on the way to Pembina ND to pick up some things my sister ordered.

Pretty cool! It's a multi part/province thing to raise money for the Special Olympics. I saw one person in youtube say they counted 141 vehicles (138 but 2 had a truck in tow or something like that).
Note the cop at the end tell me to "PUT THE PHONE AWAY!" He wasn't out of his car before that & then POOF there he is yelling at me lol. Good thing he had to stay there & not follow & give me a $225 ticket for 'using a personal electronic device IE: cell phone'.
Yet we can use a mounted GPS, video playback screen etc but not a cell phone unless it's hands free.

 

Neat. I try and join convoys when im on the road too. Must be down east as all i see is single vans ans super bees... On the west end we run turnpike doubles, and sask even runs turnpike triples! A triple pike is 3x53 footers.
