Someone wanted to see something about this.
Up to the top of Mount Hamilton, down the backside, east to the cattleguard on the top of the last hill before the Junction Bar, and back. Snow, cows, telescopes.
Surprisingly this takes almost the exact same time and energy as riding to the coast and back via OLH and Tunitas.
