MonicaBH: CL huh? Are you series? You truly must be desperate. If you don't want to carry a weapon yourself, I suggest taking along a friend, preferably someone who looks like a LEO, about 6-2, 180lbs, with a CCW and a weapon.
Oh, and the photo shoot:
Take along some props, such as a picnic blanket, basket, etc. some kind of stuffed toy and/or clicker to get the attention of the baby, a flash, a reflector, a scrim, a tripod, remote shutter release, and a list of the different poses that you want the family to assume. Assuming that there will actually be a family there.
