This challenge cache is hidden at the posted coordinates. The hide is a standard park-and-grab, but the D/T rating reflects the challenge requirements.
To claim a find, you must sign the log and meet the challenge requirements below. You may sign the log at any time and post a note, but you can only log a 'Found it' once you qualify.
To claim this challenge, get a blackout "Bingo" using the attached image. Unlike classic Bingo, which can be won with a single row, column, or diagonal, a blackout requires covering the entire card. A blackout is a variation of Bingo where every square on the card must be marked.
Thanks to Hügh for creating this challenge checker. You can use it to verify you qualify or to track your progress.
