Using My Spare Stamps In Geocaches!

I found a good use for some my of used stamps. I use them to put in the Geocaches I find. For those of you not familiar with it, geocaching is kind of like a real world treasure hunt. Members of the geocache community will hide little caches (say inside a medicine bottle) outside in parks and other public places. On the geocaching.com website, they show you where these are on a map, along with a set of coordinates and you go find it. Usually, there's a small sheet for you to sign logging your find. As an exampe, I've posted a map showing geocaches in the Lincoln NE area.

I will always insert a stamp in each one I find. I had a rubber stamp made to stamp the back with the APS website. I'm thinking, next person that finds it says "hey, look a stamp, that's cool". And maybe they'd end up investigating general info on the APS site. Geocaching is a great hobby and is somewhat similar to stamp collecting – there's history, geography, etc in both.
Here's a few pics of one I found a couple days ago. The cache was a magnetic key holder placed behind a guard rail.

Great idea. I do geocaching too and will definitely try this. Even the tiny caches that don't have room for trackables should have room for a postage stamp. I may wait for the revamped APS website before publishing their URL, but just putting a stamp in there should be enough to pique someone's curiosity. If you start seeing "Rare 1893 2-cent stamp found in a geocache" listed on ebay for thousands of dollars, you know where they came from.

Somalia?

That is a great idea. You may make new collectors.
