Case skin them for sure, raccoons are sweet streched and tanned. infacr I dont even stretch them, just salt and hang them to dry and wait till you get 5+ then make your pickle and tan them. the salt preserves them indefinitly, although if you are ready to pickle then you reall only salt for 24 hours to set the hair. I salt them and let them bone dry... maksure to scrape all the fat and stuff off with your kife before you salt. oh and DEFFINITLY wear gloves.
