Warmer/Colder (GC2M8BR) a geocache by WakeboardLanier
http://coord.info/GC2M8BR (the cache)
http://coord.info/PR1G5PK (WakeboardLanier)
You're free to copy this to your site and modify it to create a cache of your own. I do ask
though that you mention on your cache page that you got the idea and the code from WakeboardLanier's
"Warmer/Colder" cache. Thanks!
---------------------------------------------------->
<!--------------------------------------------------
Per the disclaimer above, I have adapted this code for use in http://coord.info/GC4Q92G.

<h2>Instructions:</h2>
<P>
Drag and drop the pin to where you think the cache is. I'll tell you if you're getting warmer or colder.
I'll even tell you how far away you are. If you can get within about 3 meters of the cache I'll give you the coordinates.
</P>
<P>
This is an interactive map so you can (and will probably need to) zoom in or out and pan the map.
</P>
<P>
Good luck and I hope you enjoy this puzzle and the cache!!
</P>
