Well, I for one don't find it creepy at all! MANY people on these boards meet up with other BWWers in the city for many different Broadway related events. I've done it.
I (a 23 year old gay man) live in the city, but will be out of town this weekend, or I would be glad to show you around NYC! Who doesn't enjoy showing newcomers around the best city in the world?
I hope you have an awesome birthday! Be sure to post your show reviews and how your trip went!
Best of luck!
