I often play with a couple of people who have not so great eyesight- even with glasses. I was wondering if fantasy flight had a larger map available or if anyone has any ideas/knows any place where I might be able to get a larger map that my friends might be able to read?

You can get some hand held magnifying glasses/reading screens from a dollar store for very cheap (it is a big square glass usually used for reading small text on paper). Then they can hold it over the map areas when trying to read/look at somewhere in detail.
