For those of you who would like to wheel all the different Hammer trails, I am including all the GPS Coordiantes for the trail heads, along with the names. Plug them into the search box on Google Earth and you can get a great visual!! It goes without saying, it works good with your GPS too. For a wheeling saftey tip, its a good idea to leave your coordinates with a loved one or friend who is not going wheeling with you, so if you break down, or there is an emergency at home, they know where to find you!! I also threw in YellowJacket and Truckhaven crack, which are not in the Hammers trail set, but are nice wheeling locations in So Cal.
