Major134 Blows By Cache #4000 Geocache

Transcript

There are a lot of different terms and acronyms in geocaching and I thought this would be a good opportunity to shed some light on some of them.  This list is not all inclusive but I feel it does cover a good portion.  As always, sources used for this information can be found in the show notes.

ALR

Stands for Additional Logging Requirement.  ALR’s are requirements beyond finding cache and signing the log. All ALRs must be optional for finders of a geocache.

Archive

Archiving permanently removes a geocache listing from search results. A geocache owner can archive their own listing but cannot unarchive it.  Caches can also be archived by reviewers.

Difficulty and Terrain or D/T

A 5-point rating scale using half-point increments assigned to every geocache. Difficulty relates to the mental challenge of finding a geocache, while Terrain describes the physical environment.  Simply put a D1/T1 rating would be the easiest geocache, while a D5/T5 rating would be the most difficult.

The cache was called “Major134 Blows By Cache #4000”

Difficulty rating 1.5, Terrain rating 1.5

The description read:

This is a Multi type geocache.  I am placing this cache in honor of Major134’s 4000th cache.  I am sure I have found at least 1000 caches with Major134 and they have all been enjoyable.  .

To find this cache, start at the posted coords.  Find the clue for the final location.  This cache can only be accessed:    between 9am and 9pm Monday thur Thursday  between 9am and 6pm Friday and Saturday and  between 1pm and 5pm on Sundays.  If you have seen this type of cache before, it will be easy, if not, you may have to phone a friend

Hint: Go inside

I had this one on my radar for a while and was excited when I finally got to go out and find it.  It was a multi cache outside the Spencer branch of the St Charles Country Library system.  I had seen pictures and videos of library caches online where the cache was hidden inside of a book and had been wanting to find one.  Now was my chance to find one.  The posted coordinates started out at a lamp post in the library’s parking lot.  Under the light post skirting was a prescription bottle.  Inside the bottle was a slip of paper with the author and title of a book written on it.  It read Eric Sherman, Geocaching: Hike and Seek with your GPS.  I went inside and looked up the title in the library’s computer.  Once I had the location number I went searching through the library for the section I needed.  I found the book and flipped through it.  In the very back was pocket and inside the pocket was the log.  I pulled it out and signed it with a feeling of satisfaction.  I had checked of a multi cache and a library cache off my list with one find.  I found two library caches that day.  The other was a different book but otherwise it was the same scenario.  I liked the library caches just because they were something a little different.  I hope to be able to find more of them some day.
