Probably Mormons.Never seen any, all the evangelicals knocking on my door tend to be young white Americans.
Used to see them all the time, they have a church locally, Church of the latter day Saints its called.
Don't see them so much these days, my mum invited them in for a cup tea(they don't drink tea or coffee) , big mistake, they are worse than Jehovahs witnesses or double glazing salesmen, once they are sitting in your settee and the bibles come out, you are trapped.
They are so polite and nice its difficult to tell them you wish they would get out.
