I got some new containers at the dollar store and figured one would fit in well here. 7/2022 update: well, the fake rock hide-a-key disappeared, so now it's a green Talenti jar.
Be aware of the many cyclists who speed down the Nora Kuttner trail - they mostly treat this trail as if it is Bikes Only, and don't seem to realize that it's a multi-use trail where pedestrians might be walking. For parking, either park on Laguna Road (near GC5FXKY) and cross at the signal, or park on Nicholas Drive (near GC11YP9) and walk along the trail down to Euclid. You will be safely off the trail and away from the bikes while you are searching for the cache.
