• No Double Logged "FOUND" caches allowed; Your log on each Geocache must be from the very first time you Logged "FOUND" on that Geocache.
• Once you have found the required caches to qualify for this challenge, you may then find the physical cache and sign the log, and then log your find online.
Here is a GSAK Macro that was written for a different challenge. GSAK Macro
Use it against your FOUND caches. It works to identify days that one has found different combinations of years in a single day. If you have found at least 10 in a day, it will list the day, or days, you did it on under the "02 x 10 years in a day". This will help you in narrowing down the day or days you need to look at for your qualifying caches.
When you log this cache you must include in your log which 10 years you found, and include your list of caches by GC number, cache name, date placed and the date you found them.
Your log should look similar in format to this:

Huge thanks to OF-Erad, a fellow geocacher from Colorado for allowing me to use his idea for this cache in Iowa!
