That's one reason it's not a good idea to go offroad alone, especially if it's far from where you live. Maybe if you're really experienced and know the trails but even then- sometimes people go in really remote areas where there are no phones, nothing, no cell reception, no one around for miles. And for god's sake, wear a helmet! That's really a shame.
