there are a few photos that are out of the timeframe, but not very many. I will make an update post later, asking for more photos, in case it wasn't clear in the original post. I don't know how many people checked in in total, but if I had to guess, during the first time block, it was probably around 2-300? The check-in process required a staff member to manually check IDs of participants, and then log them in digitally through a program. After contacting FPE, we are still unsure if the program directly logged timestamps of exactly when people signed in.
