Three and a half hours' worth of meandering south and east on the back roads will bring you to a highway, which leads to a smaller road, which leads to a gravel road. Even if you turn off onto the gravel road, you might miss the driveway that appears to lead to nothing but a copse of trees.
Like many of the good things in life, there are no signs pointing to it that say "This is where you need to be." Just a mailbox and a fence for the horses.
