What's up all. Been perusing this subreddit for a while and I was hoping for some advice.

Got out of a 1 year LTR 4 months back and I'm finally feeling good again. I live in NYC and I'm really, really interested in trying to meet someone in the park, train—essentially, just a public place. I'm sure there is a thread somewhere with general tips on this stuff, but if you guys could give me any advice on how you approach cold, in a public place, with other people clearly in earshot, I'd love to hear it.
