How to set up my bear bait

okay so my plan is a 5gal pale filled with meat scraps and then put a small hole in it somewhere and then get bakery expired stuff and spread it near my station. should i a) hang the bucket with rotting meat and put the bread product under neath it or b) dig a whole put the bucket in the hole and cover it with cardboard and logs. c) chain the bucket to a tree trunk and put logs on top of it. any tips on the set up and the bait are apreciated
