I get that Loomis. It is all our responsibility to know the rules. Apparently everyone thinks that an OB disc can't be retrieved to throw again. I am not sure who started that rumor....but......the only thing you may be able to get them for would be 30 seconds. Now, a Mandatory I believe that you have to leave it...but I am foggy on that, it may have changed as well...
Still, common practice in a "gentlemans game" should indicate that we help each other, because there will be a day when you will be in need of that some help.
