Undeveloped areas south of Rinaldi were substantially feral orange groves, north of Rinaldi was all grasslands. Kids would ride dirt bikes and motorcycles on the many trails in the grasslands and orange groves. Popular with the kids was "the secret of the three trees" visible on top of Oat Mountain. Kids would leave from Rinaldi hiking to the "three trees", the secret was a fourth tree behind out of sight. It was not unusual to have teen parties complete with rock band (using a generator) in the canyon just west of Tampa Ave. It was so safe in the 1970s that kids were often instructed to be in, or at least check in, when the street lights turn on.
