Oliver on Walkabout

Our desert tortoise, Oliver, has figured out that he can push on the screen door and get it open (we never latched it until today). With temperatures in the 70's, we have been leaving our kitchen door open, letting the screen door swing back - never thinking anything of it. So yesterday, a bicyclist stopped in the middle of the road and yelled for Sam, who was playing with the dogs across the street. He had seen this rather large turtle in the middle of the road and did not want it to get hit, so he stopped right in front of it and guarded it against possible cars. He was afraid to pick it up, not knowing what kind of turtle it was and I can't blame him, with a large pond visible from the road, it may have been a snapping turtle. Sam met the turtle rescuer, thanked him and picked up the turtle, explaining that he was our pet...ugh, what kind of pet do you have running loose in your house?
