I would like to use a SEO technique I noticed some are using in which they have multiple web pages which are similar but they are unique to each city in the area. I created a home page for various towns so they could index the keywords. Problem is they wont index in the site map generator.

Do i have to have a link pointing back to each page for it to be indexed?

Or is it possible to have multiple home pages unique for each town indexed?

it's not necessary to have a link to every page directly from homepage, but it's *required* that there is a way to reach any page by clicking links, starting from your homepage.
