On FM 636 there is a UFO nestled in among a stand of trees and a ramshackle wooden building or two. What is it? Perhaps it's an old abandoned time machine just waiting for the right geocacher to come put it back into service.
The cache itself is not on the property with this UFO/time machine. No need to cross any fences or go through any gates. However, time travelers coming through the time machine's portal would have a good view of any geocacher searching for the cache. It's a park (get out and poke around a bit) & grab. Not a micro, the container is a little smaller than a cigar box.
This one could be tricky during times of heavy rain. You might want to wear gloves & use a flashlight when retrieving the container. You'll be in plain sight of travelers along the highway and anyone out working the nearby fields.
Note: Terrain rating is for actual location of cache but it's just a few feet from a gravel or dirt road.
