This cache is located in Fremont Older Open Space Preserve. You should have very good signal in most parts of this park.I am deliberately not giving any additional information; please do not spoil the challenge by revealing any useful information in your log. Since this cache is not suitable for most children, the cache doesn't have any trinkets. Instead, I have left ten $1 bills. The first five parties get to take two dollars each as a reward for the "early birds". The phrase 'each party' means if three people with different geocache handles go together, it is still just one party.
