I know every inch, every bump, and every curve of highway 17 from here to Deep River. It’s quite possibly the deadliest highway in Ontario, perhaps even Canada. Hey, I drive it 5 days a week, and haven’t had any issues in 4 years, but in that time there’s been a fatal accident about once every 2 or 3 months.
Drive safely, and don’t let other drivers pressure you into driving faster. There are passing lanes every 30 kms or so.
