Of course there is never really a bad window safari. I mean out is out. There could be dogs, beach aromas (which of course would mean THE BEACH...) around any corner could be any thing.You just have to stick your head out, let your tongue hang loose, keep your eye sharp and your nose in the air. Don't forget about always facing forward because god knows, you don't want to miss a thing.
When your drivers spot something that might be of particular interest to you (they're not always right...), they will slow and often stop- letting you out when appropriate to fully immerse in doggie pleasure.
