The RUBY Daily Streak Challenge is designed to promote geocaching by encouraging people to search for boxes, solve puzzles and attend events a little more often and frequently than they might otherwise have done.
To qualify to log the Find, "Your Caching Chronology" on the Statistics Tab of your Geocaching Profile Page needs to show a "Longest Streak" that is a minimum of 122 days of consecutive Finds. The date range does not matter i.e. you may have already qualified for this Challenge at the time of publishing. Alternatively, you may list out your qualifying caches and the dates they were found in your log.
Also, it is allowed to find this Hide as Streak Day #122... your own milestone!
And as always - if you log the Find without qualifying first, then your log will have to be deleted. But feel free to sign the log in advance and qualify at a later date to log the Find.
Enjoy the challenge. I have done it myself and it does tend to become quite addictive 
The DT rating reflects the combination of 122 days worth of Finds...
