I think everyone should get cleavage avatars...
But back on topic: Keep in mind that just because you only get calls about lets say, 1 out of every 4 discs you lose - doesn't mean that all 4 were actually FOUND by someone and 3 of them just didn't call you for them.
If you followed your disc well and looked thoroughly and still didn't find it, there was probably a good reason you didn't.... that bastard is hidden GOOD. So keep in mind a lot of your discs are probably still just chillin' in a tree or under a layer of dirt and leaves.
Unless you are talking about a disc you just left in or around the basket, then you can pretty much assume if you didn't get a call, somebody just took it. So its really two different monsters.
The only times I've found discs was when I was searching for one of my own, and it sort of makes sense that way.
I just found one today in fact while looking for my one and only long straight distance driver(poor champ Valk
) Guess the guy did the same thing I did off the tee 8)
Its only the third or fourth disc I've found, and I've returned them all successfully save one, which the number wasn't connected anymore.
Jesus I am in a typing mood tonight - someone give me a 6 pack or some Nyquil, I need sleep
