Where are the best places to find bike maps with local routes and trails?

Places I typically reference when searching for this includes:

1. Most local bike shops (LBS) have local maps available or for sale.
2. Employees of any LBS are often avid riders and will hold a plethora of knowledge about the local area and trails.
3. Local trail clubs (typically volunteers that help maintain trails in an area) can be a resource to direct you to finding maps or trail information.
4. Your local Chamber of Commerce or Parks & Rec type of department will typically have maps of local bike routes.
5. Google Maps has recently introduced the ability to find directions from one place to another by bike. For certain metro areas they will route you along known bike routes or trails. When doing directions click on the "Bike" icon to tailor it specifically for bikes.
