One thing I like to do is partake in a game called Geocaching.  Geocaching is using a GPS to find containers hidden in bushes, trees, between rocks, and in other locations. Depending on the size of the cache, you can find in the cache a log of who has visited, and sometimes some trinkets like toys, coins, and other little odds and ends.  When you find a cache you take out one item and put in a different one.  On sites like, you can find caches near you and get the longitude and latitude, a description of the cache, and sometimes a hint.  Once you find it you fill out the log at the cache and online.

When using a GPS, you have to remember that GPS’s aren't exact.  When your GPS give you the Long/Lat, it is based on the time of the radio signal from some satellites to get to your receiver.  However, things like the atmosphere, warm and cold pockets, clouds, and nearby trees and buildings can change the time it takes for the radio signal to get to the receiver.  This slowdown can cause errors of usually 15 to 150 feet or more. What this causes is when your GPS gives you your location, on a good day, that location it gives you is actually within 15 feet of you, but not necessarily where you are at.  When you are finding something that was hidden, its a good idea to double your reported error distance for your search range.  If you have a 15 foot error and the hider a 15 foot error in the opposite direction on a different day, then where you are standing is actually 30 feet away from where the hider was.
Enough with the technical stuff...I have found 20 caches since I started about two tears ago.  I have also hidden two caches now, the most recent on Friday (this post is on Monday).  I hid it on the dock at Bayview Beach at N 46° 36.200 W 090° 51.884 (When I stored that Long\Lat, I had an error of 17 feet).

After setting it and submitting it on Friday, it was approved Saturday morning, and by that afternoon, it had already been found (good job chiroptera79))!  To learn more about this cache, visit here.  When you do, leave a comment on here but no spoilers!

Ohh!  The coyotes have caught something.  They are a lot closer tonight than the last time I heard them two nights ago.
