From the starting point of Helldorado, go down the wash (Strike Ravine) instead of heading up the hill. Take the first right hand turn up the short hill, just a hundred yards or so from Helldorado. Another hundred yards or so there is a prominent road to your right, but you want to take a left here. This is the start of Lockjaw. It is pretty short (about the same length as Minor Threat), and is up hill most all the way. It is moderate in difficulty, but fun, with one pretty tough obstacle. It is not nearly as difficult as when we first created it, however.
