Please do not attempt to get the required information by land. If possible at all, doing so would require trespassing on private property. You will not need to get out of your boat until you get to the final step. Each step has a different location saved as a waypoint in the cache listing. For each step, go to the location specified in its waypoint and follow the instructions for that step below. After you have gotten all three pieces of information, you will use the formula at the end of the listing to find the location of the actual cache.
You will need a boat to complete this cache. Please note that no gas or diesel powered boating is allowed on the lagoon. Boats may be powered only by sail, electric battery, or by person power. You will be able to use any allowable kind of boat to find this cache.
There are public boat launch locations at Leo Ryan Park, Boat Park and other locations on the lagoon. I have provided waypoints for the two main boat launch locations. There are a number of amenities on the lagoon listed on the City of Foster City website at https://www.fostercity.org/parksrec/page/water-activities . Some of these may be useful for finding this cache. The first stage is nearest to the boat launch at Leo Ryan Park. Finding the cache and returning should take from half an hour to two hours or so depending on what kind of boat you use and where you launch your boat. The terrain rating is five only because you need a boat. The lagoon is often calm and you will not be boating through any difficult passages or rapids.
Stage #1:
The cache’s listed coordinates will take you to a pretty inlet off the main part of the lagoon.
On the shore you will see a storage device for a particular type of vessel. The storage compartments are numbered. What is the number of the upper right compartment when looking towards the shore?
A = [The number of that storage compartment] + 549
Stage #2:
Look to the East shore ( on your left coming from stage one ). You will see trees that look like they should be in a Dr. Seuss book towering over one of the homes. How many tall Dr. Seuss trees are there?
B = [The number of Dr. Seuss trees] + 7
Stage #3:
You are near the end of another inlet in the lagoon. Look on your right facing the end of the inlet. There are small statues sitting on the edge of the shore in front of you. How many are there?
C = The number of small statues + 1
Stage #4:
The cache is located at N 37 32.A W 122 15.B0C
I hope you enjoy your tour of the lagoon!
