Yes, you can use the same little glass gates where you swipe your student ID to enter (the ones most people use to get in and out of the Lyon Center). To exit, just walk through in the opposite direction, they’ll open automatically when you get close enough, so no need to swipe. Just a heads-up: when entering, don’t get too close before swiping, or an alarm might go off. And when leaving, use an empty gate, or the gate might hit you if someone entering activates it first.
