Finally received my remote shutter release, a wired one, and I’m really enjoying it. If you have a D700 and don’t mind waiting an entire month for deliver, you can get the same thing here(it’s a direct link to the product, just click it and it will take you to the product page):
I can hang my camera from my neck, check the horizon line by using the mini-level I have on my hotshoe, and keep the trigger in my pocket and shoot like that. It adds another level of “discreteness” to my candid shots.
