IQ Test #2 was cache find number 1,000 today.

This puzzle cache stumped me about a year ago, although I didn’t pursue it very hard. I plotted the waypoints on a map, thought I saw the start of a pattern, but couldn’t figure it out. I never did try computing azimuth and distance between the waypoints—something that is mentioned in the description. That proved to be the key, and the solution to the puzzle became readily apparent.
I wasn’t sure I believed my answer though, because it was about 50 yards from another cache. I decided to go ahead and check and sure enough, found the cache.
Using “findstats” on all my cache logs, I get the following:
1000 unique caches.
