In college, I shot sports (football games) with my Pentax K1000. Mostly at night. In crap light. We pushed Tri-X 400 as far as we could. Since we were only shooting for the college newspaper, it was good enough.
Funny...at the time we didn't think anything of it. I've got a shoebox full of what I flatter myself to think are really awesome shots. A modern DSLR with auto-focus and see-in-the-dark ISO? That would almost make it too easy!
