Other Thoughts:
Morley Field is the course that I learned Disc Golf on, and for that reason I appreciate it greatly. When not crowded, Morley is a great course to play and a fantastic practice course. However, when it's crowded, I would rather spend my time throwing drives in a field for practice.
San Diego desperately needs more courses to accommodate the hordes of people that play Morley Field any given day.
