If the temps are as low as you said, providing you handle it properly, the meat will be fine for four or five days but obviously the sooner you get it out the better. Bear meat taste is definitely affected by what they have been eating. If they're on apples, acorns, berries or manzanita (which in B6 that time of year they will be looking for acorns if there are any) they should taste great. If they've been on fish (especially when its late and they're scrounging rotten fish) or eating most any rotting meat they tend to be disgusting and inedible, at least to me. If your butchering them and not making sausage then fat sows are hands down the best and yearling boars next (up to you if you want to kill sows). I don't care for older boars but for sausage and pepperoni they're o.k. On the right bear I really like roasts and steaks as well as the ribs. You can also have the hams smoked like pork and its damn good. As mentioned above canned, sausage and pepperoni sticks are great. Taylors in Cave Junction, Or. has the best reputation for pepperoni sticks but they are pricey. There is a guy in Mad River on Hwy. 36 that does a good job too.
Since you mentioned you've never hunted them I'll pass this along - find the feed, find the bears. Bear will travel an awful lot of miles to find feed if they have to. In the fall they will be looking for acorns, preferably white oaks or live oaks but others if they can't find those. Rarely will they eat black oak acorns. Just because an area holds lots of bears in the spring or summer means nothing come fall because the feed source changes. Have fun and good luck!
