My chums and I have two principle rules losing/finding a disc.

1) No disc left behind

2) If you find a disc, it's yours unless

(a) someone else calls you out on it or

(b) if there is a name/number on the disc, you call if the area code of the phone number matches the area code where you found the disc.

Great article, I believe many people can attest to all the things you wrote.
