The Grangerson Sheperson feud is symbolic of the civil war. The Shepersons would represent the north and the Grangerfords would represent the south. In the novel the Shepersons win. This is similar because this is the exact outsome of the civil war.
Anglers can find spiny lobsters in warm water areas like the Caribbean, Gulf of Mexico, Florida Keys and off the California coast. Most people dive for spiny lobster or use hoop nets, while they use lobster traps, also known as lobster pots, to catch clawed lobsters.
Remember they are not Maine lobsters and don't have claws. They are usually easy to catch by hand wearing gloves. You don't want to get a cut by their spiny carapace as a wound can some times get infected. Another method is to use an Hawaiian sling, pole spear, or 'tickle and bully net'. Keep in mind you must be 200 yards off shore to use this method or spear any fish. Spiny Lobster happens to be the biggest food export of the Bahamas, understandably with so many islands and the plethora of reefs.
