Things we learned while driving through Canada to Alaska

We were there in August. and i'm like you Canada was scenic and almost all the towns we were in were nice and clean. the hiways were clean much more so than Alaska. Alaska just seamed to be run down every were you looked. I was wondering how Canada keeps there hiways so clean. they don't have a bottle refund like we do here in Oregon, that helps in keeping them off the sides of the road. I wasn't impressed with Alaska.
