More on the sad news

The cacher's handle was Smokey Stover. You can see his finds here. From his log entries it sounds like he was really enjoying himself. His final log entry is eerie:

It was getting late afternoon and I didn't want to fight rush hour traffic and the low sun so I'll wait until later to chase after #3. This is fun.

The cache he was attempting (#3) was a bonus cache, the third in a series. He found the first two to get the coordinates of the third.
