(Three runways, two intersections and a lesson in geometry.) While doing touch and goes at my home airport...
Tower: Experimental XYZ, cleared to land 17, hold short of 35.
Me (without thinking): Roger, cleared on 17, hold short of 35.
(Several seconds later.)
Voice on frequency: I want to see this!
Another voice: Me, too!
Tower: Uh, Experimental XYZ, make that hold short of 22.
