Depends on your skills and the town needs. Bakeries were in short supply years ago, most bread was flown in. Towns that are snow bound all winter were heavy into drinking so opening a bar might be profitable if you don't mind encouraging them to drink all winter. If you can weld or do some other skill perhaps open a trade school of some kind. If a military base a tattoo parlor or payday loan store.
