I'll throw out an interesting curveball about market indexes. This may go back two decades but there was supposed to be a mutual fund exclusively devoted to the casinos in Nevada. I may be a little fuzzy on exactly what happended but I beleive it never came to pass because of the downturn in the economy circa: 1978?

The concept is still viable to pool resources and create a CASINO CHIPS & GAMING TOKENS COLLECTORS CLUB MUTUAL FUND, read: investemnt club made up of chip collectors?
