I will be taking my nice camera along next time. I'm currently designing a carrying system in my head for the body and lenses which will protect them. from blunt force trauma in the pack :D
I'll probably take one of my two nice prime lenses and a zoom.
As far as her staying under the tarp in the rain I think I've trained her to do that actually. She loves to sit out in the rain on the porch... but I wont let her anywhere near my hammock if she's wet and muddy. I've camped out enough in the back yard in the rain that I think she's made the connection to her-being-wet = no-laying-with-daddy
