This "heat map" image overlay in google earth shows density of geocaches in Maryland, Southern PA, Northern VA and part of Delaware. I got the idea from watching a soccer match where the "heat map" showed where the ball spent the most time. There is also one that is weighted by favorite points, and a blend of the two. http://bbs.keyhole.com/ubb/ubbthreads.php?ubb=showflat&Number=1455605 Tell me what you think!

This one has been on the bottom of the river (about 5 feet deep) for a month so far with three finds. No water inside yet. It's a wide-mouth water bottle with an o-ring seal. Log and some small items are in double-bagged ziplocks. On the bottom at 5 feet means boat motors can't hit it. Explore the listing to see how it's found. http://coord.info/GC2AGVN

http://www.geocaching.com/seek/cache_details.aspx?wp=GC2AGVN is a underwater cache on the bottom of the river near a favorite swimming spot. Paddle to get there, but also a unique find. I will probably remove it for the winter and re-place in the spring.

I used an wide-mouth water bottle with an o-ring seal. Dry so far after 4 weeks at about 4 feet depth. Photos at http://www.geocaching.com/seek/cache_details.aspx?wp=GC2AGVN
