I spent yesterday afternoon in midtown manhattan. In the span of about three hours in midtown, I accumulated three of these visitor badges.
Union Square Ventures is located in the Flatiron district between Union Square park and Madison Square park. It's not a high end office location. And one of the great benefits of working in and visiting companies in the Flatiron district (and Soho, Tribeca, the Village, Chelsea, etc) is you don't have to spend five minutes getting through security.
I realize why we have this security in midtown and wall street. I lived through 9/11 too.
But given the choice, which fortunately I have, I would never locate a business in one of these high security buildings. It's a pain to visit them .
