As with anything that deals with minimums and maximums, there are numbers usually associated with them. In Geocaching, there are numbers, titles and owner names. This challenge cache has a minimum # of CO names you need to qualify for the yellow smiling face! Therefore.....
Thanks to Geocaching HQ, who had the idea to chase various size containers using a satellite constellation as a direction finder, and President Reagan, who opened up GPS signals for civilian use, we have a little fun game/sport/hobby/obession (for some) that makes many people question others and their sanity.
In motorsports, you have, for example, the 24 Hours of Le Mans (maximum of 24 racing hours), the Daytona 500 (minimum travel of 500 miles) or Bristol Motor Speedway racing (minimum of 500 laps on the bullring of a track). 500 is such a round number that it'd be too easy to do a cache requiring 500 cache owner names. 501 is usually associated with Levi jeans; therefore, I am going with 502!
So..... WELCOME ladies and gentlemen to the Cache Owner Gnames 502 brought to you by all geocachers alike!! You will need to prove by posting in your log or attached to your log you have found a minimum of 502 different cache owner caches! (Disclaimer - I had this idea and then found a similar cache in the Midwest of the same ilk for 500 & 1,000, so it is not a tribute; however......imitation is the sincerest form of flattery.)
This is a grandfathered challenge cache; therefore, project-gc.com is not required to be used to check your qualification. A simple screenshot of your overall number of COs (502 minimum) attached to your log of this data would suffice for the requirement from those sources. Please see my 4 examples of acceptable verification screenshots through the following links that you can get the overall number of COs (502 minimum) for posting:
My Geocaching Profile will look like this:

GSAK Find Stats Macro will look like this:

GSAK Cache Owner Macro will look like this:

Project-GC will look like this when you using the Challenge checker:

(WARNING: A link in your log to project-gc.com verification will not be accepted. I will not chase your profile to see if you qualify since I put the cache out there. It should not be hard to post or attach the data requested. If you chose not to post what is required, then I can chose to delete your log. This is a 50/50 arrangement and one you agreed to when you signed up for GC.)
You won't need to remove the cache container from the spot. Please respect GZ and the surrounding area. The cap is on finger tight and should be recapped the same way. The log can be removed and replaced in the cap easily enough, so please put it there and not stuffed into the container to ruin it for others. Please maintain the spot a bit if it begins to look disheveled and out of place so others may enjoy it also. Of course, any enhancements you have in mind to extend the lifespan while at GZ are also welcome, including any coord suggestions since I used my Magellan and Samsung to get numbers as close as possible to actual GZ.
CONGRATS to WingsAndTales for the FTF with ngrrfan and hiking_fool for STF! Let the caching begin!! Start your cachemobile or cachecycle!
There is no room for trackables and coins in the container.
Watch for wildlife and respect their domain.
Caching can be dangerous. There are inherent risks involved which you take upon yourself when you are caching.
Please be careful and remember rule #13 - HAVE FUN!
