Monster meet this year, over 2300 people signed up. Yesterday was somewhat sparse, with only the 1000 free and 1650 free on tap. Here's a shot from today, I suspect tomorrow will be even more crowded; there are 128 heats of just the 100 free on the schedule!
(Note: Most the people in the stands in the above shot are actually participants, not spectators).
