ChiefGeocacher: Greetings!
This appears to be near a school, or on school grounds Glenwood Landing Elementary School. Please correct me if I am wrong.
Please refer to the section of the Geocache Listing Requirements/Guidelines document captioned "Off Limits Areas," and you will see that geocaches are NOT allowed at or near elementary and secondary schools. This rule was added due to the rising number of law enforcement/security incidents involving either a bomb squad callout or reports of suspicious persons.
