You know another thing I like about agility is the mental/thinking part. You have to analyze the course, set a strategy and then follow though on your plan, which may or may not work. It is a different challenge every time.
Sometimes thing look simple but there are traps, restrictions and optical illusions so you need to learn the little tricks to make it work. That straight looking line might not be so straight and that curved broken up line might indeed be straight. Then add the dog who doesn't know anything about what is going to happen and control them with something as simple as the turn of a shoulder, your speed(slowing up or down) and position all at high speeds is just darn exciting.
To me, a person who likes puzzles, it is very appealing.
