Bear meat is among the best game there is. Need to take care of it though. That means getting it cooled down as soon as possible after you kill the animal. It's warm this time of year, and the meat will spoil quickly if you don't properly take care of it. You should know where a cold storage/locker plant/butcher shop is in the area before you step into the woods.
If the folks you will be hunting with are telling you to forget about the meat, their ethics in other areas are suspect as well. Not familiar with the laws in Minnesota, but it may also be illegal to leave the meat. Regardless, it's unethical to do so. Why kill it if you're not going to eat it.
