With growing tensions in incidents in Europe, has anyone traveled over there recently? Especially in the last couple weeks? I last visited in 2007 (Paris,) but with almost-daily incidents of violence, I'm getting to be a bit apprehensive & anxious. I've heard some reports that people have said that security is noticeably increased, I will be traveling to Naples, Florence, Rome, Cannes, Marseilles, & Barcelona. We generally will be avoiding metros & be very aware of our surroundings, but now with incidents happening in large crowds, it's a bit daunting!
