Beach front property - Invest for the future

Our family home was on a lake shore, in the Pliestocene. The current shore of Lake Ontario was some 3 miles north. My Father explained that he never had good timing on real estate. So here's your chance. Get out a topographic map, guess how much sea level will rise due to glacier and ice cap melting, and buy land at the appropriate point above sea level. But get going on this because a large percentage of the world's population lives near the coast, and they're going to get displaced. Oh, man, the payoff on this investment could be huge! Never much liked Long Island anyways. HT Greg Laden.
