For the claustrophobic, I would suggest coming up from the west
side of the cache instead of the east side. You'll know why by
reading this
article.
Off Highway 90, you can actually get within a half of a mile
from the cache. Deceptive! Don't pull over on the highway! Do some
research first.
The recommended starting point is 47.39279 -121.39311
If you have more problems, I would suggest going to 47.39489
-121.44736 for a hint on how to get to it. Just print out this page
and use it only if you have real problems.
