I parked in the NE corner of the huge FedEx lot at the end of Sundial Rd. and went up a paved path, around a locked gate and over the dike/40 mile loop trail to the gravel trail described by others. The sparrow flock was no more than 100 yds in - near one of the "Wildlife" gates. There is a No Trespassing sign posted next to the gate near the parking lot. Up on the dike and along the gravel path are numerous Port of Portland signs and one shot-up Reynolds Aluminum sign.
Are we guilty of trespassing to access the top of the dike/loop trail?
