Make sure you are planning ahead to see a show!  All FoCoMX venues operate on a first come, first serve policy and their may get to capacity. Also many venues have their own security screenings procedures, so just because there is a line it doesn't mean the venue is full. Things you can do:

1. Plan your schedule and have a back up plan in case a venue is full
2. Get to your venue with enough time to get through security
3. Be patient, the venues are processing folks as quickly as they can while keeping people safe
4. Have your ID and wristband ready!
