FYI .. for those who haven't heard ... a "team" from MIT won the DARPA 
"balloon hunt" (find and report the location of 10 tethered red weather 
balloons located in the continental USA first) .. less than 9 hours after 
the official start.

>> $40K for finding 10 WX balloons.
>> That should be a piece of cake for APRS...
>> How about a collaborative effort... and
>> share the locations with the prize being
>> spent on APRS projects where they can do
