I've not realy thought much about holding anything non-camera non-lens equipment dear but now that I think about it it is probably one of my camera bags. My first camera bag which I got from my grandfather. A yellowish one came with a Praktica SLR. Must be a Praktica bag because a few years ago I got another Praktica SLR and it came with an identical bag.

Anyway my first trip out with my grandfathers bag was to the PFA rally in either 1996 or 1997; and I used it just last night when I went out for a walk. I have been using it for the last few months. Despite me having other bags this is still the one I take out all the time.
