This hide was orchestrated by my 1st grade son. The closest public parking is at the Mill Creek Sports Park overflow lot (N 47° 52.372 W 122° 13.168), then you'll be walking south down the trail just shy of a half mile. If you want a longer stroll you can park in Mill Creek Town center and proceed north up the trail.
If you see a picnic table with a park style barbeque next to it then you're in the right spot. The cache is not located more than 5 feet off the paved trail and you don't need to go beyond any fences.
A couple geotokens are available for the FTF honors... congrats to MaddiesDaddy on the FTF!
Many thanks to the Mill Creek Parks and Recreation department for supporting Geocaching in their park system. Please support them and their wonderful parks and trails.
