The cache is NOT at the posted coordinates. ALSO, DO NOT PARK ON 74TH AVE W! That is a private, residential street with NO Parking Signage. IF you do so, you park at your own risk.
Please DO park at the Parking WP that I have provided.
This is a bonus cache for completing my Adventure Lab Cache "My Mountlake Terrace Tour (MMTT) - Falconer Edition". To obtain the final coordinates you need to complete the Lab Cache. Pay attention to the journal entries at the lab cache locations. You will be given the coordinates for this cache with the journal entries.
The hours for this cache are dawn to dusk.
Good luck. Keep calm, and cache on. Congratulations to Foreverlost1 for being FTF!
