"How?!"

"Do you have a camera bag?"

"No."

"Well here's a camera bag and a bunch of other stuff, too."

My grandfather, Fozzie, had all of this photography equipment. I don't remember him taking photos all that much, although I do remember watching a slideshow of his travel photos one time with my whole family in my grandparents' basement. 

I am very excited to have a tripod, some different lenses to try, and a large enough bag for all of my equipment. Now, what do I do with these old cameras?
