I agree with a couple other posters on this thread. If I throw a disc in a lake and I don't take the time or spend my resources on retrieving the disc, tough titties (my grandma used to say that when life seemed "unfair"
). How in the world can I get mad at someone who grabs their snorkel gear and dives for discs when I am not willing to go in the pond/lake myself and do it? We all have the same opportunity to dive/search for our discs, the only difference is these guys do something about it. I knew where the disc went in, I didn't grab my mask and strip down to my skivvy's, this equals me giving up my right of ownership, end of story in my opinion.
I also don't mind paying a guy money to get a disc back that I threw in the water. I was out a Jericho Lake course in Aurora IL and there were two young guys diving for discs in a notorious spot that always gobbles up discs. Not only were they out there finding other discs but they would go get your disc right then if you paid them $5. I had no problem handing them 5 bucks because I wasn't going to wade out in the water 20 ft offshore in that nasty water filled with glass bottles and fish hooks to get my disc. And I had no problem with them keeping my disc if I wasn't going to pay them for their efforts. I guess I just see this topic differently then others, but I'm ok with that.
Let me also say that I hand back discs that I find (ask people on the course, cuz often times someone had just left it a during that round), put them in the drop box at WW's, throw them in the box at DD and DGW, and even call the numbers on the discs.
