What is the best way to handle the threat of deer on rural Ohio roads, especially at dawn and dusk?

1. Speed up to clear deer country quickly
2. Slow down in posted deer areas, scan the shoulders for movement, use high beams when traffic permits, and be ready to brake straight, not swerve, if a deer enters the road
3. Ignore deer crossing signs because they are old
4. Honk continuously while riding through deer country
