You can park right next to the cache. No need to go beyond the pullout or fence.
If you're lucky, you may see cows grazing among the ruins.
Historical intel from slugslayer: "This pasture used to be owned by the late Tom Buller, aka 'Bubba,' with whom I worked for several years. He considered the old cars in the pasture 'parts cars,' and would not part with any of them because he might need them some day. He once felled an alder on my head when I was a green laborer and turned my back on him. Broke my hard hat and I saw stars but was ok. He was full of great sayings like 'only fools and flatlanders predict the weather.' R.I.P. Bubba; gone but never forgotten."
