This is kind of curious. My trip up to New York was completely uneventful. On my way out of Penn Station I noticed soldiers (National Guard, maybe?), all unarmed. I wasn't sure whether they were working or just in transit, like me. Now, on my way back home, I noticed soldiers at Penn Station again (unarmed, so what's up with that?) - and then on my train (the 5 pm southbound) - police stationed on the train, in between every car. I've never seen that before - is this normal, or are they looking for something? Very strange...
