ha,ha you guys might be right.

however, looking at the gravel isn't the optimal way of determining 
focus authoritatively, if you are aiming down at a vertical subject, the 
focal plane isn't  perpendicular to the ground, and given that it 
intersects near the top of that vertical subject, it will be intersect 
the ground somewhere in front of where that subject stands.

oh the trials of a one-inch depth of field!
