There are, generally speaking, five sorts of people found on Cape Cod at one time or another: native residents, natives who are not residents, residents who are not natives, summer residents who are natives, and summer residents who are not  natives.  A sixth classification…is the group known as ‘guests.’ Native residents have had company all their lives, as have summer residents who are natives. These hosts are fairly casual about guests, seeing them as a natural and inevitable part of any year – like ticks.’’
