My cell phone signal is really iffy out in the woods. 90% of the time they know when I leave, I tell them how long I intend on riding, and the general area I'm going to be riding in. The kids and I have names for all the trails so they would know were to find me. Even if Mack is working I call him when I leave and when I get back.

So's ours.... we bring it with us, but lots of places there's no signal and you'd have to climb to the top of a hill for it to work.
