At 5 minutes and 6 seconds after 4:00 a.m. on the 8th of July this year (2009), the time and date will be the name of this cache: 04:05:06 07-08-09. This won't happen again until the year 3009, by which time this cache will probably be muggled.
I left an obvious prize not for the FTF, but for the FTF after 04:05:06 07-08-09. So if you want the prize, get out there shortly after 04:05:06 07-08-09.
Bring your own pen, and please replace the container carefully.
It was a little tough to get good reception here, so I used the average of four readings. Please let me know if the coords seem off so I can adjust them.
