Rabbit Holes - Searching for Alice

....But if the watchman see the sword come, and blow not the trumphet, and the people be not warned; if the sword come, and take any person from among them, he is taken away in his iniquity; but his blood will I require at the watchman's hand." Ezelkiel 33:1-6

The following is a list of rural underground access point indicators. . A well maintained branch road leading to a little used park or recreational facility.
2. Electrical power lines that are routed near facility, when such routing results in longer line length and/or routing over a natural obstacle (mountain, river, etc.).
3. Electrical power lines or substations much larger than visible local load requirements.
4. Large reservoirs that serve no apparent useful function. Example: not needed for flood control or civilian water supply, or that have larger capacity than is required for presumed function.
5. The presence of truck traffic on rural roads with no known destination, or inappropriate truck types for apparent destination.
6. A public park or recreational facility that is maintained at a level well in excess of other nearby facilities, especially if facility less well known or used than other nearby facilities.
7. Public facility personnel (park rangers, etc.) that are overly nosey and/or suspicious of your activities, especially if personnel occupy the site on a 24/7 basis.
8. Public park or recreational facility where part of facility is fenced off, or accessed by a gated road, or otherwise made inaccessible to the general public.
9. The presence of inappropriate or unusual structures and/or construction methods. Examples: small cinder block building with an electrical power feed normally used on major office buildings. An unmarked, but well maintained trail in public park. An old building (possibly abandoned) with a new door, and expensive lock.
10. People at camp grounds that seem out of place. Example: improperly dressed, or using inappropriate equipment, or having unusual accents (these are people taking a recreational break from underground facilities).
11. Well maintained roads that are not shown on maps, or follow a different route than shown on maps.
12. A noticeable lack of wildlife (birds, small animals, insects, etc.) in a location that would normally support a large wildlife population (see 1.2.4 preface).
13. Any of the applicable indicators listed under urban rabbit hole detection. Example: unbalanced traffic flows, etc.

As with urban rabbit hole detection, this list is far from complete. It is intended to illustrate what sort of indicators to look for, when searching for rural underground access points. Again, all of the techniques employed in urban rabbit hole discovery are applicable to rural underground access points. However, it must be stressed that rural access point detection and observation is far more dangerous. Not only are there less people to hide your activities, but a larger faction of those people who are present will likely be rabbit hole occupants or guardians. Failure to exercise due caution may lead to becoming an unwilling underground guest. For this reason, the author suggests one or more of the following precautions.

1. Be very discreet in rural underground access point observation.
2. Always inform a trusted friend of your intended destination and expected time of return.
3. When possible, use a group recreational outing as cover for your activities.
4. Spread your observation activities over several months, at random times and days of the week.
5. Assume you are being watched at all times, and act appropriately. i.e. As somebody who is enjoying a day in the park
