Walk indoors at your local mall in the winter months when the icy ground and early darkness may compromise footing and sense of security. 

Join a local community effort to make your streets, parks and neighborhoods safe.  Join the Neighborhood town watch - they walk the hood in pairs or groups.  See out your local "Rails to Trails" affiliation.

Alter your walking routes and times of day - try not to be predictable.  

Let other know where you are: whether hiking, biking or just out back gardening.  Bring your cell phone with you.

Have an indoor activity plan for bad weather days or when traveling to unfamiliar destinations.
