Definitely wouldn't say the OTC tags are a "scam." The open bull areas are tough, but if a guy is looking for a fun hunt and would like to fill the freezer an OTC tag can be the ticket!! You can hunt cows or spikes on some of the best limited-entry elk units in the world. Can't chase the big boys, but that doesn't mean it isn't fun to be there! I've killed a bunch of elk with OTC Utah tags.
Better choices out there...Colorado, Idaho, etc...for hunting bulls OTC, but Utah elk tags are available and a lot of fun.
