A friend of mine that owns land adjacent to the ALE (Arid Land of Ecology) had a few friends out riding horses on Saturday May 3rd, as they were cresting a hill they spotted 4 guys miles out on Hanford land. As they watched them they noticed they were running back to their truck, obviously because they had been spotted. The horseback riders galloped down to their truck, at that point the trespassers decided to hide in a dip still on Hanford land. The truck was full of hunting gear, spotting scopes, beer and packs. They parked on private land at the fence line of ALE (which clearly stated no unauthorized entry). The trespassers Finally came out after 1 hr and 45 min by the time they saw the horseback riders leave over a hill. By then the landowner was at the fence line and they continued to walk to their truck with FULL PACKS. The 4 men are from Chehalis WA said they were shed hunting and had permission, but got scared and hid when they saw people on horseback. (Then why hide if you had permission?) They said they had been out there all weekend and last weekend. As well as one trespasser said he had just got a $500.00 ticket for trespassing on the Wenas Elk Feeding station two days prior. When dispatched, the authorities also stated the same individuals were caught trespassing 3 weeks ago and were caught on another part of Hanford land. Keep an eye out for this blue dodge and these trespassers. They ruin it for the rest of us!
