The cache is NOT at the above coordinates!
You must first complete the Old Town Irvine Adventure Lab by downloading the Geocaching Adventures app (available for ios and android). You can scan the code below, click the hyperlink above, or view the lab cache on the Geocaching Adventures app at the above coordinates to begin your adventure through historic Old Town Irvine. Total estimated time from start to finish (including finding the final cache) is roughly 30-45 minutes. This cache is intended to be walk / dog / kid friendly.
Hints for the bonus will be given in 4 out of the 5 journal entries. In 1 out of the 5, a code word will be given to enter into Certitude below for the final coordinates (and an additional hint). Use stealth and BYOP at the final. Please replace the cache exactly as you found it.
You can validate your puzzle solution with certitude.
