I drive through Renfrew County a lot, it's a beautiful drive up to North Bay. Deep River is a nice little town, but it's a recently developed "planned community", built for the Chalk River Atomic Laboratories.
Petawawa is of course very Conservative. If soldiers are anything like my cousin, then they are a pretty hardcore bunch.
There is one spot along highway 17 with a Cheryl Gallant billboard, only it is rather small and somewhat buried in the forest, so it's kind of random and not very visible. It's really weird. But then again, so is Cheryl.
