Well, it's been a solid 3 years and change since anyone's posted on this forum, so I figure now is as good a time as any to try and revive it. My family recently took a trip to Miami, and I managed to spend a day at KMIA as my first real attempt at spotting. I only ended up staying for a few hours, but saw a ton of variety. All in all, definitely a good experience.
