Set a new World Record for Speed caching.
We found a total of 413 caches in one day.
August 29th 2009 - Midnight to Midnight
Denver, Colorado, USA
We just wanted to see if it could be done.
We had 4 cachers in one vehicle.
We started by waiting across the street from the first cache until exactly midnight.
At midnight we ran across the street and started searching.
The weather was perfect.
Total Mileage Driven = 471.5 (1.08 miles per cache)
Total Caches found/Dnf'd =413/23
Average cache time = 3 Minutes 18 Seconds
