One thing I have noticed: IF you stand still in a place where everyone is moving, you also stand out. People will approach you with questions, comments and offers. Example. I was waiting outside the Metropolitan Opera House at Lincoln Center right before a performance, and in the space of fifteen minutes five or six people approached me to ask about tickets- did I want to buy any or sell any?  I had no idea there was such a lively commerce in opera tickets.  Earlier this month at a LIRR station (that's Long Island Railroad) I was waiting for my sister to pick me up, and I ended up in a long conversation with a gentleman from Mexico,( I believe  he thought I might be Hispanic, ) who wanted some money, and ended up settling for a discussion about the difficulty of finding work, and what it's like to live in the middle of PA. Does this happen in State College? I don't think so, but maybe I don't stand still that much when I'm home.
